The location is everything! Melvin's place is right behind Gran Via and it has access to metro and busses. It is also near all shopping areas if you like to shop, and it is within walking distance to Plaza Mayor.
The apartment itself is small but it has everything you need; the kitchen might be a little bit tight if you want to cook but it's not a big issue. The bed is very comfortable. The table is a bit tilted, I guess it is something that needs to be fixed but other than that, everything is great!
