Melvin's place is inexpensive, but not the most comfortable I have stayed at. The apartment feels like it really needs a little character and updating, also the corridor and entry door are a little sketchy and might not be the best place to re-enter at night. The beds are incredibly uncomfortable and the apartment sleeps 4 at best. It was noisy for the entire night, so much so that it was difficult to sleep with neighbors partying early into the daylight hours. The upside was that Melvin was very communicative when the wifi wasn't working and when we ran out of bathroom supplies. He also agreed to store our bag which was wonderful. Value was good for Madrid at the height of tourist season, but I'm afraid the noise and discomfort put a bit of a damper on our trip.
