This is a fine, basic standard flat in the very center of Seville, well suited for shorter or longer stays. I lived here for five weeks in March-April, while working here, and had my wife and two children visiting me during a holiday. There is plenty of space for one person, and it also works fine in a few days for a family. I was very satisfied with the flat and have nothing to complain about as regard any of its facilities.
Prepare for some street noise in the nights of the weekends, but in that respect, this place is probably no different from any other place in the city center.
The owner is very nice and helpful if any question or problem should appear
