Martas apartment is a calm oasis in Madrid. It is in a Standard building, with two security doors. But Inside the apartment was nicely renovated, everything was clean and new and had been nicely decorated. There is plenty of space. The kitchen and bathroom were hotel standard-great shower- washing machine was good and there was an outdoor line to hang the clothes on. It was nice to have the little balcony too.
Marta meet us on time and was really friendly and showed us around the place as well as giving us a map and recommending some sights.
We walked most places but there are a couple of very close metro stations that make getting anywhere really easy. Nice comfortable place, Would definitely recommend.
