Overall: We enjoyed staying in the apartment, the neighbourhood is wonderful, the view from the balconies is impeccable, and the apartment had everything we needed.
But: the pictures are somewhat misleading. The apartment has probably been used a lot since the pictures were taken, and the furniture seemed dirty and worn down. It would also have been nice to be advised that there was a big construction site on the ground below which meant quite a lot of noise from 9 A.M till 6 P.M. every day. Luckily the apartment is on the 6th floor so we were not quite as disturbed as we could have been - but still it would have been nice to know beforehand.
The communication with Joaquín was great; he responded swiftly to our messages and was very helpful.
