Great location, really close to most parts of town you need to be, plus Sant Antoni itself is great for a number of good restaurants and bars (and quite a number of great gin bars!). The flat itself is spacious and would comfortably fit 4, though we were just two people so can't attest to one bathroom between 4 people. The flat was a little cold in the winter even with heating, and has thin walls so light sleepers might have some issues. Other than that, no real problems and we enjoyed our stay here.
