The location of this tiny apartment is superb. It was well appointed although I would not have wanted to actually cook in such a small space. I don't think a couple could easily stay in such a room and for a single person, it might be better to get a room in a shared house, where you could exchange some information with other visitors. The host arranged taxis for me from and to the airport which turned out to be very helpful but the person who let me into the apartment was not very forthcoming with helpful information. So, for your information, the nearest supermarket is in Calle de Hortaleza and it is a good idea after you arrive to walk to Plaza Mayor and visit the tourist information office as soon as you can.
