We had a really nice stay in Bibi's appartement in Sevilla, everything was clean and it'snot far from the cathedral and other sightseeing highlights.
There is a supermarket right over the street, which is opened until 10pm, which is very nice to have.
The only thing we didn't like is that there is not really a window and the street is directly behind the door (on the right side of the kitchen) so you can hear people talking and cars driving by...
