The apartment is very clean and tidy - perfect size for two people. The air conditioning is great, the facilities good too. Wi-Fi is a little slow. The communal areas are clean but faintly smell of smoke - someone else in the building perhaps. The location is excellent if you want to be right in the centre of Madrid (short walks to Chueca, Sol, Gran Via all on your doorstep) but not particularly pleasant late at night - be aware if you have young children or particularly vulnerable. Otherwise we had a great week and the communication from the owners was excellent. Thanks!
