We enjoyed our stay at Raul's place. The place is very clean and very centrally located in Madrid. Most of the major attractions were reachable by foot. The nice thing is that the building has an elevator too. We just faced a small issue with the hot water in the shower the first day when it went away after some time and we had to wait 40-45 mins to get hot water again. The remaining days were fine. Apart from that, we thoroughly enjoyed our stay.
