Hi Susana,
thanks for letting me and my family stay at your property and have a really good time in Madrid. Anyway, there were some issues with the apartment that I communicated and there was no follow up or fix during my stay. The water heater was malfunctioning and the AC unable to cool the place to the desired temperature (22c). I really think that the premium price of the apartment must have this working properly. I burn my hand and my wife her back dealing with the heater on/off hot/cold water, luckily the kid didn't got hurt
