Alberto's apartment is a great place to stay while in Sevilla. Although it is not really central to the historic part of town, transport links are good and there are regular buses to and from.
The apartment itself is perfectly clean, spacious and located in a very quiet area. There's a nice little balcony, air conditioning and wi-fi... as well as a few treats supplied very generously from Alberto for the arrival.
Communication with Alberto was super easy, he replied to any questions I had within minutes and seemed to be available to help out at all times.. he even picked me up from the train station to bring me to the apartment.
I'd definitely recommend this place, but advise that you be aware that that the location isn't the most central..; that said, it's no huge deal and well worth the money. Thank you Alberto!!
