Fabio's place is really great - its really well furnished and the whole building, filled with hanging plants, is really nice to be in. It is also incredibly cool, amd great to relax in after a hot day.
The area around the flat is really good, there are lots of great places to eat and drink, a good market. It is obviously a trendy area - there are zero plastic stores, and lots of interesting stores. All in all it is a wonderful place from which to explore Seville, and also to escape from the busiest parts!
