My husband and I stayed here for 3 nights and it was wonderful. We did not meet Javier but our check in was smooth and he was easy to keep in touch with via email.
We have been travelling for many weeks so it was nice to have our own space. We were able to wash our clothes and cook at home. There was laundry liquid, oil, salt/pepper/spices, tea/coffee already in the apartment.
The bed was comfortable, and the apartment was mostly quiet although you could hear the gate for the garage open and close.
An excellent choice to stay in seville, walking distance to all attractions and the cathedral is just around the corner.
Highly recommended.
