The flat was amazing and located in one of my favorite area in Sevilla. Two rooms, absolutely clean, air conditioner (really important !), in a nice building ! Perfectly located : you're at 20-30 MAXIMUM by feet to all the main areas in town (20 min to the arena, 15 min to the city center for shopping, 30 min away from Triana).
Marcos was a great host : everything you need in a flat, equipment or breakfast was there ! There even were maps for us ! He gave us a lot of great advices to enjoy the city. I would highly recommend the flat, the host, and Sevilla
