We (my boyfriend and I) stayed in Javi's apartment for 4 nights and we can really recommend it. It is the same as described and as you can see at the pics. Late arrival (11 pm) wasn't a problem, Javi was waiting for us in front of the building and then we got great tips for Madrid. The tapas bar "Lateral" in Chueca was our favorite! La Latina is also a great place to stay, so the apartment is well located. Just around the corner there is a very nice café "la encantada" where you can have a typical "desayuno madrileño" (tostadas con tomate).
Thanks Javi for giving us a home in Madrid.
