The design and location of this stay was absolutely stunning. The setup makes it feel very spacious and it is located within walking distance of so many attractions in Madrid, including the Museum of Illusions which was a blast. the place is also located just blocks from two nice grocery stores and it has a fully stocked kitchen with very nice pans, knives, and dishes. the surprise bonus was that it has a washer/dryer! there was some street noise, but no noise from neighbors.
the only cons are that it is a walk-up (2 flights) and the lights are bad in the stairway (not always on). the other con is to be careful which way you walk outside as some parts of the neighborhood are sketchy. but overall we felt safe.
if you are looking for a place to stay in central Madrid, this place is a hidden gem.
