I loved this place. It is centrally located — It is literacy 10-20 min walking distance from major museums and the major shopping area. It is also near a subway station as well as a bunch of bus stops. So getting to places is super easy.
The unit itself was very clean and had everything I needed. There is a full kitchen. I didn’t use it to cook anything but if you wanted to cook stuff, you could certainly do it. Also when I was in Madrid, it was 100F everyday, so one other plus of this apartment is that the AC is very powerful. I actually got a bit cold at night and had to adjust the temperature.
Lastly the apartment has a small balcony. I enjoyed opening the balcony door and enjoying a cup of tea in the morning looking out before I left to do touristy stuff. This is definitely a place I would love to stay at again when I visit Madrid again!
