My family and I (4 guests in total) stayed in Asun’s apartment for a week. It was perfect. The air conditioning was amazing in the summer heat (it was c40C most days). There is individual aircon in each room. Each room is very spacious with plenty of storage. The location is brilliant: everything is within easy walking distance, without feeling touristy. The kitchen is fully equipped (although admittedly we didn’t use it!) and the coffee machine is very good. The roof terrace was lovely, especially in the evenings, and you can even see part of the Cathedral - although it could have done with more furniture.
The floors are connected by a large spiral staircase and meant that the apartment felt very open. The rooms on the first floor have a wall of glass so you can see in from the sitting room - although there are very effective blinds to ensure privacy.
Asun was exceptionally fast at responding to all queries - the best host I have dealt with on Airbnb. There were nice touches such as fresh fruit and orange juice.
It is a wonderful apartment and we will definitely stay again if we return to Seville!
