This Airbnb is AMAZING. We were a group of 8, and we had plenty of room to sleep and hang out. The real gem is the private roof, with a jacuzzi, comfortable outdoor furniture, and an unbeatable view of some of Prague's most iconic landmarks (castle, clock tower, etc.). The location is also great, steps away from Old Town, Charles Bridge, and lots of great restaurants, bars and clubs. The apartment is on a high floor (elevator in building) so noise was never an issue.
The hosts were gracious enough to write up a full Prague guide that our group took full advantage of, including recommendations for restaurants, bars, coffee shops and sites to see. They were very responsive to any questions / concerns I had before we booked, and were great to deal with.
Overall, I would recommend this Airbnb to anyone. It truly made our experience in Prague special, and made it really convenient to tour the city. Many in my group noted that this was the best Airbnb they've every stayed in (especially because of the rooftop!). We'll be back!
