I have mixed feelings about this place. The location is great, everything is clean and well thought about. You're in the city center and everything is at a walkable distance.
Yet we had some issues with the keys stuck in the door (might be our fault but we were not warn by Filipe), some cockroach (but I guess there is not much they could do about it in this kind of historic flat) and some hot water issue (but it was corrected very fast by Fernando).
Overall a very good experience though.
