The apartment is not luxury but perfectly adequate for a home from home feel and we enjoyed it. It is fitted with all the equipment needed, particularly important, a good shower and mattress and linen. A second reading light would be a good idea.
It is situated in a residential area, quiet apart from some noise from the rumble of cars on the cobbled street below. Not too bad as it is on the 5th floor. We were unlucky to have a power cut after a stormy massively rainy day with no elevator for 2 days and another day after that, so maybe not so good if a person is not so mobile.
There are 2 railway lines not far so it is possible to go to the centre of the city or more. Otherwise it seems that taxis need to be used. We did not use the trains as we were visiting our family with baby grand daughter nearby and from there we used taxis. A nice park, Plaza Arenales with shops and cafes/restaurants around are a walking distance away. The area is pleasant, trees along the streets. Just watch out for dog dirt.
