The best aspect is the location, vet close ro most of what Warsaw has to offer. Short walking diatance to central railway station and airport bus (bus 175), shopping, cafés, restaurants, and supermarkets (Biedronka) literally just around the corner, 15 min walk to the royal castle and the old town.
Our apartment was big, at least 60 sqm so lots of space, very quiet, but dated. Esp the kitchen felt dated. But if you are fine with a convenient, spacious apartment that looks a little antique, then you will most likely be satisfied here.
