A very nice apartment with high standards. We were two families of three (children 9 and 10 years old) who shared the apartment. Were were there during hot weather so it was very nice to have air conditioning in all rooms. Washing machine and dishwasher was also quite convenient to have.
We especially appreciated that it was in a residential area, with lots of good restaurants around and not so "touristy".
On the small street behind the house there were plenty of really good restaurants that served tapas and pinchos (uncertain about the spelling).
Also there are lots of food- and vegetable stores all around.

Still very centrally located with easy access to the central parts of the city.
Our host was most forthcoming and met us at the apartment when we arrived. We also got help re-book the taxi when we had to leave early due to a strike at the airport.
One thing to remember is to make sure to close the elevator door, as it doesn't close by itself.
I would highly recommend this apartment.
