The apartment is located in a hotel, so there is easy access 24 hours/day thru the front lobby. When there are many other guests, at times the elevators are busy/occupied and you have to wait. Also you can hear noise from the hallway very easily thru the door.

Rosa's family member Manuel met us at the apartment and showed us around. The furnishings were comfortable, though the kitchen was small (but we ate out all the time anyway, so that wasn't important to us), and there was a nice view toward the north of the city. WiFi was not entirely reliable, we had to go down to the ground floor to try and improve reception.

The neighborhood is awesome -- close to the riverfront, a short walk to the center of Sevilla (ie, cathedral, Alcazar, etc), full of bars/cafes/etc, and there are at least a couple of grocery stores right downstairs. Don't feel like you won't get an authentic experience by staying in Triana vs Casco Antiguo with all the other tourists; we even enjoyed watching the Spain vs Turkey futbol match with the locals one night!
