This is the best located airbnb in Sevilla, without a doubt. Feria and the Alameda de Hercules neighbourhoods are full of all the beauty, people, bars and conveniences you could ever want. if you stay here, make sure and go to Vizcaino's, los callos, flou, Lola's and the cute Italian tapas place opposite (tiny bowls of fresh pasta to die for). These are all literally downstairs from the flat and the best tapas and drinks in the city.
also go to Feria market just up the road for fresh fish and vegetables and cakes and enjoy the huge flea market outside your balcony on a Thursday.
It is a very short and pretty walk to all the key sites, including las setas, the cathedral/alcazar and waterfront (triana too)
The balconies are stunning in the apartment and we were very comfortable always.
Jose David is great and met us really late in the evening (after a long flight) at the flat to let us in and give us plenty of tips about the city. he also spoke superb English, even though we made him speak Spanish to help us practice ours !!
can't reccomend this place enough, we had the best 11 days here and hope to return ASAP
