The apartment is nice, clean and has a large tarrace. There is no lift in the building however it was not a problem for us. The bathroom and the apartment are rather small, however for a couple it is perfect. The apartment is in the Triana district, close to the cafes, tapas bars, restaurants and the riverside. The windows to the tarrace (which can be fully opened) are suprisingly good at protecting the apartment from the sounds of the street and nearby church bells.
Sofia is very friendly and helpful in providing a lots of useful information.
Highly recommended!
