Luis' and Ana's place is great; located very central you can reach everything in a few minutes by foot (bars,restaurants,supermarkets, museums,nightlife) and at the same time it is quiet at night allowing for undisturbed, quality rest after a long day (seldom the case in such a central location!).
The place was very clean, well-equipped, and nicely furnished. There was not a single issue during my 4 week stay; and Ana and Luis were nice and accomodating hosts, always available and offering their help should something have come up.
Muchas gracias!
