We were here with my wife and child in 2018 during a conference on therapeutic nutrition. We lived for 3 days, then according to the plan we went to Valencia, to the sea. We really only had to do nothing, mostly spend the night. Comfort was required mainly because of the baby - the daughter had just turned 2 years old, and they would have taken the guest house.
A normal, very comfortable hotel. The staff is polite and English-speaking. It is really located next to the metro. But at the same time, it is actually one of the central districts of Madrid, so it was even more interesting to walk. The hotel has its own restaurant, but there are only breakfasts, then it's like in a regular cafe. But it was just the right time for us. The rooms are comfortable, bright, and the bed is clean. The beds are comfortable. Everything is in good order in the bathrooms, there were no problems.
