This apartment was absolutely perfect for a four-day visit to Seville. It's ideally located in the heart of the charming Triana neighborhood right on Plaza del Altozano at the end of the bridge and the start of the Calle San Jacinto pedestrian street, so there's lots of activity that you can watch from the balconies. The Mercado de Triana is right next door as well, and the Jamón supermarket is a few short blocks away. There are lots of restaurants nearby, all of which which cater primarily to locals and provide a more authentic experience than anyplace in Barrio Santa Cruz. Nacho recommended Las Golondrinas (as did Rick Steeves) and I wish we had gone there a second time.
Everything in this apartment is as it looks in the photos. It has modern appliances and decor (and easy-to-set air conditioning!) yet is cozy. We cooked a couple of meals and found the kitchen to be very functional – I liked that I could close the door so that cooking smells wouldn't seep into the living room. The beds were especially comfortable. I stayed in three other Airbnb rentals during my recent trip around Europe and I had the best sleep in this one.
Although we unfortunately didn't get to meet Nacho in person (his friendly brother checked us in) he was very communicative leading up to and after our arrival. He's a great host and answered all of our questions. I definitely would stay in this apartment again and was happy to have found it.
(Note: if you are looking for peace and quiet and/or go to bed early, you may want to look elsewhere. Due to its central location there is noise from the streets until about 11-11:30pm on weekdays. Not sure about Friday or Saturday since we weren't there on those days. I'm a night person and didn't mind, as the location was very appealing.)
