This place really is perfect, great location right by the cathedral but quiet enough at night that you won't be disturbed. You can easily walk to the old town or the new parts of the city. The living room and kitchen area is well designed and comfortable but the real star of the place is the outside balcony areas, particularly the upper area with its view of the cathedral. Perfect for having a cup of coffee in the morning or a glass of wine in the evening! Note there are a few steps to climb but they are well designed and not too steep.
We visit Seville regularly to see family and have stayed in many Airbnbs, this might well be our favourite so far!
