Wow. Wow. Wow! That's all we could say when we first arrived. The apartment is stunning! Everything is brand new and so modern & elegant. The studio is set up so nicely it almost feels like a one bedroom. The bathroom is set up so that the toilet is in a separate room, which is great for cutting down getting-ready time in the mornings. The place also has a beautiful little balcony overlooking the courtyard. There is a washer/dryer combo unit in the bathroom that worked great! Their TV is pre-programmed with Netflix and the wifi works well so we were very happy campers.
The building is very secure and on a nice quiet street in Mala Strana. It's only a 2 min walk to Cafe Savoy and a bridge to Stare Mesto (Old Town), and less than 15min walk to Prague Castle! If you want to hit the tourist destinations, we highly recommend staying here. It's perfect - you're close to the castle, the sculpture garden, Lennon Wall, St. Charles Bridge, Clementinum, the astronomical clock, dancing house... literally everything, as well as tons of great cafes and restaurants, and you don't have to deal with the crowds of Old Town.
All in all, if this place is available, don't pass it up! We've stayed in multiple AirBnBs in Prague and this one is a rare find!
