I highly recommend Carlos' apartment. It has all the necessary accessories and comfort to spend a pleasant stay. It is located in a quiet area but close to a lively neighborhood with lots of good restaurants. The balcony is a real plus to enjoy both sunbathing during the day and the cool of the night.
The communication with Carlos and Susana was fast and efficient. They did not hesitate to answer any questions we had. Susana even gave us many addresses to eat and drink and recommendations of things to visit in Seville. They also let us to check-out later to be confortable with our departure. This was really appreciated !
If the opportunity arises, I will return to Carlos without hesitation
