Javier’s place matched well with the pictures and descriptions. We had a great time staying there for nearly two weeks. The neighborhood is very lively, but the street is mostly quiet, except before and after football games. (The stadium is two blocks away, and particularly after a victory could be a little noisy for a while, and then during the cleanup afterwards.)
There are a number of restaurants in the neighborhood — we particularly enjoyed Manu Jara for breakfast, or to bring croissants back to the apartment. There are all the amenities you could need — banks, the Nervión Mall, El Corte Ingles. The Nervión metro station is about an 8-minute walk, and then 10 minutes to downtown (Puerta Jerez station), and Santa Justa Train Station is perhaps a 15 minute walk as well.
We had a couple of small glitches early in our stay (one entirely our fault), but Javier and his crew were very responsive and able to resolve the issues quickly and painlessly.
I can enthusiastically recommend this place to anyone who wants a taste of neighborhood living in Sevilla! We look forward to returning on our next trip!
