For me the most important thing is the location , and the location of Melvin's appart is in the heart of Madrid, so you can access the main attractions by walk.
The welcome was warm and Melvin offered us a bottle of wine a s a welcome drink, and I would like to thank him again for arranging a taxi for me who was on time.
In general, I will recommend the appart for it is good location ad the good service from Melvin.
