It's great value, cheap, not too far from the center. Niko was very flexible and was always fast to respond.
The room was very clean and comfortable, although the fact that it only has a very small window which opens into the kitchen is kind of strange, but it's no issue at all.
The only bad thing I could say is that the kitchen isn't very well equipped. There's no oil to use, one small pan, one small pot and a few basic items, but unless you want to heat something premade, there's not much to work with.
All in all, we had a wonderful time in Prague, and it was a great affordable option. Would recommend to anyone!
