Very pretty, minimal and modern home. Nice touches like fridge supplies and a comprehensive guidebook. Great location to head to many parts of Prague if you don't mind climbing the stairs to get in. Diego mentioned at check-in that the apartment was recently renovated.
WiFi (T-Mobile CZ hotspot) was almost unusable even with strong signal. Stayed in February with outside temperatures around -2C, apartment was fairly cold and the radiators didn't seem to keep up well and didn't have individually adjustable thermostats. I like the cold so didn't mind.
The bathroom was pretty, but functionally needs some work. Bathroom sink was a wimpy trickle of water that's annoying to wash your hands or even clean a toothbrush with. Seems like there are hot water supply issues, if you turned both showers on the temperature would drop significantly. Granted I was staying alone and turned the second one on just for curiosity, but there's not much point in having double showers if you can't use them at the same time. About 5 or 10 minutes into the last shower I took the hot water ran out completely and I ended up using a wet towel to sponge off soap in the cold.
