I stayed at this hotel for five nights, and it was flawless. The staff were all friendly and helpful. The breakfast was adequate for the price. The room was clean, and the toilet and bathroom were perfect. The room I stayed in also had a bathtub. If I ever come back to this area of Madrid, I will definitely stay at this hotel again.
It is really in the center of the city. It's very easy to get to everywhere tourists want to visit.
Single room is cozy, but clean and well enough to have a sleep. Breakfast is tasty, but variation is limited. However you can easily find cafe/restaurant around the hotel, so you don't need to care.
This hotel is close to Metro Opera station, a 3 min distance.
The room space is limited and no desk to open a computer.
Breakfast is not attractive and an Ok grade.
