I stayed here for 4 months on exchange in Madrid. It is a lovely small room with everything you need in the bathroom and kitchen. The room is also close to 2 metro stations that tạke you to Sol or Retiro easily in 20 minutes. There are many shops closeby and 24/7 supermarkets just a few blocks from the house. José is very responsive and will be there when you need help.
It is a great place to stay if you're studying or traveling in Madrid!
