Javier is a very nice person and made me feel comfortable from the very first. The flat is fine. The bedroom is very basic as are all the accommodations. I would say that a number of investments could be made to improve it: a more stable desk in bedroom, a doorknob that doesn't fall off, and a better working toilet.

I very much liked the neighborhood but I suppose it depends on what a visitor wants. It's not at all tourist-y. If you want to see a "normal" Madrid neighborhood, this is perfect. Actually, it's better in that there are significant immigrant communities, and I especially loved the two Moroccan restaurants I ate at, following Javier's suggestion!

It's about 1km walk from the Metro which might be an issue for some with mobility issues or carrying a lot of luggage. And, Javier shares his place with one permanent flatmate but also rents out another room in the same flat. So, there are four bedrooms, two of which are rented via AirBnB. Just FYI. It was quite quiet and I had sufficient privacy.
