Javier's place is nestled right across the street from the historic Teatro Real. If you're looking for a bargain, but also want to be downtown in the middle of it all, this is the place. The particular room I was in didn't have any windows, so if you don't mind not having sunlight, then you should be fine. I had some minor communication issues when checking in and which button to ring the building to get into the building/unit, but it all worked itself out. Javier and his sister were super kind and always made sure that my stay throughout my time there was optimal.
I recommend this place!
