Zuzana was easy to communicate with. The apartment is as described - up lots of stairs - consider it your workout for all the yummy food etc in Prague!
The entrance may be a little off putting & the street it’s in but the apartment was very spacious and cosy. It’s also very dark if you arrive at night in winter. Lights in the stairwells are on timers & hard to find in the dark. It can be a little noisy from the street despite being 4 floors up. We enjoyed our stay a lot & it was good value for us. Key collection was straightforward but off site from the apartment. We used the company Zuzana recommended from the airport. Our driver was fantastic and very helpful. Would recommend this service especially at nighttime.
