I have stayed 5 nights at Eva's amazingly cool apartment which was located at the heart of Malasaña, making everything easy and convenient. The room was super lovely, clean, spacious, and comfortable. I think I have slept into a coma for a few nights. Eva was an excellent host, warm-hearted, friendly and responsive. The only pity thing is that I couldn't stay long enough and hang out together :) I would definitely recommend it and for sure will come back again when I am in Madrid next time.
