We had a lot of fun in Nieves' apartment. It's very well designed. it has a beautiful view. On the terrace you can enjoy the sea, sunrise or sunset. This could be the only reason why you should rent the apartment. The Citycenter and the beach are only 15 min by walking.
However, it must be expected that you can only get to the apartment back by taxi, because the apartment is on the kind of Hill. Walking would be very exhausting.
Lastly, I would like to say that the accommodation could be very difficult on the warm days, because there is no air conditioning in the apartment. We were there in September so we didn't have any problems with it.
I can just recommend that apartment.
