Great place for 1 or 2 people. It's just as advertised, very clean and a good size. The location is excellent, very near to the main locations of the city as well as being very close to both Atocha rail station and a metro station with access to the rest of the city.
Daniela and Cesar were also very accommodating and answered quickly to my messages. My train arrived late at night but Daniela and Cesar still arranged a very smooth check-in and gave me very clear directions for checking in.
I definitely recommend this stay.
