Mariano's place is a very good option in Sevilla. The apartment was impeccably clean, the couch and the bed are confortable. The kitchen is perfect to make some homemade tapas. But if you don't wanna kook, the location is a very good bonus, the Alameda de Hercules Plaza-like is 5 min far from the apartment, there is full of bars and restaurants.
My stay at Mariano's place was very nice and I recommend a lot!
