María is a friendly and calm person. Although we didn't see her very often, we felt very welcome at her flat. The apartment is quite small, but we had everything we needed. The room is nicely furnished and the bed was very comfortable. You can not really use the balcony, but the view from the window is amazing. The best thing about the apartment really is the location. It is super central with two supermarkets right next to it, lots of bars and restaurants nearby and you only need 15 minutes to walk to Plaza Mayor. So all in all we had a very nice stay in Madrid.
