We liked the apartment a lot! It is in a great location in the historic center of Sevilla, with everything on walking distance. The castellar street is wide enough for a taxi, so you can be dropped off before the door, but it is also quiet so that you are not bothered with street noises.
The furnishing of the apartment are very refined with marble floors and a efficient and nice kitchen. The beds were good. The two single beds are in a part of a room that has a low ceiling.
Highly recommended !
