It was a great pleasure staying at the apartment. Due to the fact that the location is in the centre of madrid and right next to gran via, it is great for exploring the most well known attractions and locations in the city.
The room was cleaned perfectly and in addition to that we were able to place our luggage in the apartment even before the checkin time. The cleaning lady was also extremely nice and she even spoke english.
The communication with the landloard worked perfectly. Every question I had was answered in a few minutes.
One small downside was the noise of the boiler that is placed in this specific room. But it is not that loud and it takes no time adjusting to the sounds that appear occasionally.
All in all it was greats and I would highly recommend it.
