I stayed in Jorge and Maria's apt for 3 nights. The location is a real plus as it is situated 1' from a metro stop and around 15' from Madrid's central square. The neighbour is very lively, as there are a lot of bars and a 24h Super market, but a little bit noisy as well. The room was clean, well equipped and the internet was very fast. Jorge was very responsive in his mails and helped as much as possible. In overall I would recommend it to someone who is searching for a lively place near the centre.
