I don't think I can say much that others have not said. The location i absolutely perfect. It is easy walking distance to all of the places you want to see. There are restaurants galore, too many to choose from within a half kilometer radius.
The place was as clean as any I've stayed at. A cleaning staff would clean the place once or twice a week on demand. They not only cleaned it spotlessly, they folded up a few items of clothing I had left.
A few people had previously commented on pedestrian traffic noise. It exists but I found that if I ate late, as the Spanish tend to, the noise was almost gone when I went to bed.
The building and the entire area felt totally safe. You need to go through 2 locked doors just to get in the building. The building is quite dark in the hallways at night. I quickly learned to turn on my phone light when entering or leaving at night.
One of the reasons I booked this place was free cancellation. Vicent was more than accommodating. I had to rebook my flight due to some incomplete covid paperwork. I emailed Vicent to advise of a next day arrival. I got an email in reply very quickly offering a refund of the first night's stay. That is a generosity not often seen. Thank you.
If I was coming back to Seville I would definitely stay here again.
