The location of the apartment is fantastic, in the middle of a trendy neighbourhood, it is within close proximity to many of the main tourist sights and has many bars and restaurants, as well as a supermarket near by. We didn't actually meet Cristina, but she organised for the keys to be picked up from a nearby cafe. The apartment is slightly more worn than the pictures portray, however everything was in good condition and working properly. The air conditioner is a necessity for Madrid in August, however as it is only in the main living area, the loft bedroom was far too hot to actually sleep in, luckily the fold out sofa is reasonably comfortable and a sufficient trade off in order to deal with the heat. Overall we had a good stay at Cristina's but some of her rules do seem a bit over the top.
