Late and last minute delays
It was ok. Guide was nice and knowledgeable. The tour company changed the meeting point last minute after we’d already arrived after paying for an Uber. Then delayed the meeting point last minute by 20 minutes so we had to walk to a new meeting point and stand around in the heat for 25 minutes. Not great.
Response from the operator: Thank you for your review; all the comments help us improve and consistently provide quality service to our customers. We apologize for the inconvenience with the meeting point, but we truly hope you enjoyed your visit with our guide and that we'll have the opportunity to meet again soon for another experience!

A Must See!
The tour company was very helpful and Amanda, our tour guide, was outstanding. Such a great personality and extremely knowledgeable. She made the tour very special and also gave us an awesome recommendation for lunch after the tour.
Response from the operator: Thank you for your review. We hope to welcome you back soon for another incredible experience!

Why this scores 52
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Rome : Ticket and Tour Underground San Clemente & Roman House: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Rome.
How much does Rome : Ticket and Tour Underground San Clemente & Roman House cost?
+
Prices start at $35 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Rome usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Rome : Ticket and Tour Underground San Clemente & Roman House take?
+
Plan for about 1 hour from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Rome is not rushed.
Is Rome : Ticket and Tour Underground San Clemente & Roman House worth it?
+
It holds an Outty Ranking of 52 out of 100, which we label "Worth a Look". That score blends traveler sentiment (4/5 across 3 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Rome, and how flexible the cancellation terms are.
Can I cancel or reschedule Rome : Ticket and Tour Underground San Clemente & Roman House?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Rome : Ticket and Tour Underground San Clemente & Roman House suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 1-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Rome : Ticket and Tour Underground San Clemente & Roman House?
+
Around 1 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Rome can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Rome and add a light layer if any part of the 1-hour experience runs outdoors or after sunset.
Where does Rome : Ticket and Tour Underground San Clemente & Roman House start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Rome within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Rome?
+
Rome runs on skip-the-line access. The Colosseum underground, the Vatican before opening, and the catacombs south of the walls all require a licensed operator, and the price gap between the good ones and the rest is smaller than you would expect. We rank by guide credentials, group size and how reliably the promised access actually materialises. On Outty we rank every Rome experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Rome Pasta and Tiramisu Class: Ravioli, Fettuccine & Fine Wine 5*, Pasta Making & Wine Tasting with Dinner in Frascati from Rome, Rome: Pizza & Tiramisu or Gelato Class with Flowing Fine Wine 5*. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Rome?
+
April, May, September and October. August is hot and half the city is shut. Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Rome?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
