Our stay at Lenka's place was great! It perfectly accommodated our group of five. Communication with Lenka was timely and informative. The apartment is spacious with comfortable beds, good wifi, and hot water. Also, it's only a short walk to Old Town Square and the Palladium.
There is a club on the corner and the bass can be heard until about 5 or 6. It didn't affect our stay but just be prepared if you are a light sleeper. We are very happy with our stay and would love to stay with Lenka again upon our return to Prague!
