it's like an 5 stars hotel! I higly reccomend Luis's flat! nice, cozy, perfect position, with the best host ever! belive me Luis will host you like his son/daughter, will help you whathever you need, will show you the best of the city and will treat you like a king/queen.
the room it's small but have everything you need (tv, air condict., desk, wardrobe and fridge!) you have your private bathroom with a nice terrace.
it's been a pleasure been there and I hope to visit Siviglia again cause it's gorgeous!!
