We stayed at this apartment in August 2019 for 2 nights with a group of 14 friends. and had a wonderful time.
Firstly, the location is excellent, around 10-15 minute walk from most of the best attractions in Madrid. The place itself is very beautiful and stylishly decorated with plenty of comfortable space for sleeping, socialising and eating. Many reviews comment on its cleanliness and I must say they are completely right!
I would highly reccomend this place for a group of friends or family travelling to Madrid, you will not be dissapointed!
