We had an amazing stay with Maria in Sevilla. The cute apartment is close enough to the historical part of the city so you can walk there easily, but still far away enough to have a silent environment outside at night.
The apartment was spotless, with nice towels and a working AC. Julio, who welcomed us was very nice and informative. Messages over Airbnb were read and responded to very fast by Maria, English and Spanish both worked fine for us.
However we are a couple and do recommend the apartment only for couples. The bed is a bit small (you shouldn't be taller than 1.80m and like to cuddle) and the kitchen is not roomy enough to cook a full meal. We were staying for 2 nights and only ate outside, so it was perfect for our needs.
The AC needed to run the whole night, since our apartment was on the top floor and with 39° being in Sevilla, there was no other option, but therefore we had a little seating area outside the room, which is supposedly shared, but we were the only ones ever using it.
With that being said we can only recommend staying here! :)
