Good location and value. Apartment was clean and looked the same as in the pictures, albeit a bit smaller than I had imagined.
Check-in and check-out were quick and easy.
Ancap answered messages with a bit of a delay, but otherwise communication was very good and they gave us tips for things to do in Prague.
We had problems with the beer tap in the apartment but got it working eventually. The biggest issue was that we never got hot water in the apartment. No instructions were left on operating the water heater, which might be a good thing to have for guests in the future. But besides the water issue, everything in the apartment was wonderful.
