I had a very good stay at Gei's place, the studio is new and clean (it is in the process of upgrading some furniture). The air conditioning is very useful as the large windows let in a lot of sunlight which means it can get hot otherwise. Location is quite good, right above the bus stop that goes directly to Madrid central station (bus 85), and 2 minute walk from metro. There is also a swimming pool available. The reserved underground parking is also especially useful for those traveling by car. Checkin was also smooth and hassle free. I highly recommend Gei's place over other listings in Madrid. Book with confidence.
