We had a great time in Sevilla. The flat is beautifully decorated, very spacious and clean and it has everything you need, including coffee and tea. Though it is in the city center, it is very quiet at night. And the bed is very comfortable for a good night sleep.
The internet works great and there is also a cable tv with Spanish channels.
The flat is very close to a supermarket and shops and within walking distance of tapas bars and the city center.
The communication was great. We arrived late in the evening and Sergio greeted us at the apartment. He also gave us recommendations for places to eat and directions to popular places to visit.
I would recommend the flat to anyone visiting Sevilla.
