I rented this apartment for my parents and their friends (in their 60s) visiting me in Madrid. They never met Melvin as it seems to be like a hotel-apartment, an prompt (and cold) employee came to give them the keys (1 bunch of keys per couple) but one key was not working. There’s only one widow in the apartment (in the kitchen) so the apartment is quite dark (no day light in the living room nor the bedroom) and it’s quite difficult to ventilate the place. The apartment is badly sound-conditioned, you can clearly hear the neighbors talking and walking around... Bring ear plugs! But they slept good and everything was clean. The location is between Santo Domingo and Callao Station, near Gran Via street which is great for shopping.
