Great little apartment right in the centre of Madrid! Compact but with pretty much everything we needed for our stay - no iron and even tho there was a washing machine it wasn't for guest use, however we didn't need either during our stay. It was comfortable for 2 of us but I think it would be a bit tight for 4 (there's a sofa bed in the living area). Located down a quiet street, there was no traffic noise at at, but occasionally some noise from the stairwell and courtyard tho nothing significant. The location of the apartment couldn't be better - it is easily walkable to all major attractions/sights, and a metro station is about 150 metres away if you need it. There are s multitude of cafes, bars and restaurants very close to the apartment, along with several convenience stores nearby for groceries. Juan was very pleasant and showed us how everything worked when we arrived, and is available by phone should you need to get hold of him. Wifi worked well and everything was very clean. Recommended!
