Communication with the host and access to the apartment was excellent. This is where the good experience stopped. Being a loft style apartment the only door was to the bathroom.which had a mould covered shower wall- you don't get to see that in the photos. The kitchen tap was dripping LOUDLY without stopping... We asked the handyman who let us in to fix this and he promised he would come back later that day to do so. We went out exploring only to come back late in the evening to find nothing had been done. What followed was a sleepless night listening to the incessant dripping and trying to get comfortable in a bed whose mattress should've been replaced years ago (a huge dip in the centre) and was not meant for two people.
The next day (a Saturday) Liliana informed us that she could not find a plumber in the whole of Madrid (a city that never sleeps) who worked on the weekends to fix this problem and she wanted us to wait till the Monday and spend the next 48 hours with a dripping tap and no sleep.
The best thing was is that we were able to cancel our booking and get a full refund thanks to airbnb customer care who were excellent.
Beware of the pictures they do not show the reality of what the apartment really is.
