Our stay at Isa's was nice.
The flat is decorated with taste and has AC everywhere.
Isa was really nice and responded quickly. She agreed on us leaving our suitcases for a few hours after check out so we could go for a walk and enjoy our last day in Sevilla.
The location is good too. You're only a 20min walk to the Alcazar and the center and there are nice restaurants, bars and markets around.
We would definitely stay at Isa's again if we go back to Sevilla.
