We stayed 4 nights at Melvin's and it was one of my best experiences . The flat itself was small but also had enough space. Everything was clean and new but the shower water pressure was a bit low , however I was able to take a shower everyday. The location is perfect , near to almost every sightseeing place in a walking distance . We met one of the colleagues of Melvin who was so nice and friendly. Everything was organised perfect and they also offered and booked a cab for us to the airport which was perfect. I want to thank Melvin and the staff for everything. Will stay here again when going back to Madrid.
