The apartment is really well situated, in the heart of the city. It's spacious, clean, good light, the AC is working really well.
We've never took the bus or the cab, we only walked.
The rooftop is really nice as well. But the light are missing in the rooftop the night and the rooftop's floor could be fixed at some place.
Otherwise it's a really nice place, I do recommend it for everyone visiting Sévilla :)
