I lived in Enrique's apartment for a handful of months during my student exchange program. From pre-arrival logistics to my stay in Madrid, he was very communicative and responsive. You can't beat the location, which is just a short walk to grocery stores, shops, restaurants, bars, the metro, etc. It is in such a lively part of Malasaña, but the soundproofed windows keep the place quiet and tranquil. The neighborhood itself is very sweet and I felt very safe walking around. I definitely recommend Enrique's apartment!
