I had a long stay in Nelson's apartment. The apartment is in a great location next to Bernabeu stadium, 15 min walk from Nuevos Ministerios transportation hub and 5 min walk from the subway line 1, with many supermarkets and restaurants in the area. The appliances are modern and work well, apart from the TV that sometimes randomly loses signal. Also, the remote for the air conditioning was not the official one and some buttons were not working.

On the not so nice side, I would say the apartment is smaller than what it looked like from the pictures. It's ok for a single person, pretty small for a couple although I guess it's fine if you are only spending a couple of days visiting the city and just want to come to the apartment to sleep. The house itself was very clean when I got in, apart from a bad surprise with the bed sheets that had some large brown stains. Not nice but at least Nelson agreed to come and bring new ones.

Nelson was very nice and responsive every time I had to contact him and even brought some biscuits from Amsterdam.

All in all, I had a nice stay apart from the problem with the sheets but would only recommend the apartment to people that do not need a lot of space and do not need to stay in a very comfortable apartment.
