Staying at Melvin's was really good. Him and his assistant were nice to us, so quick via text message (him) and showing us the flat (her). The house was really central, near the main attractions and both metro and cercanías lines. It was was really simple to reach everything we needed (supermarket included). The house seemed a little bigger in the photos but it was very comfortable. The only thing I would change is that there was only a small window in the entire apartment: this was a little uncomfortable especially during the hot days, since the flat gets hot and damp. But in general, the quality-price ratio was good. Totally recommended!
