The apartment was small but very comfortable, it has a very good position, it is directly in the city center. I really enjoyed christmasy Madrid by reaching all touristic places by foot. The room was very clean with a good view only the sheets for the bedroom after the portable washing had stains, which left a bit uncomfortable feeling.
The host is very welcoming, responds very quickly and gives directions.
The only negative aspect were the neighbors that happened to me. In an other small room directly next to mine stayed a couple, which made a lot of noise at night, especially on Saturday night they brought their friends and in four people from 3 a.m till 5 a.m they made the most of possible noise, laughing continuously, listening to music, smashing doors and shelves. And this was happening as in their room as in the kitchen, they were feeling like they were alone, they left only round 6 a.m so immagine I did not sleep all the night !
