It’s a very nice hostal close to Plaza España.
The rooms are quite small, but clean and facilitated with a good bed. The only disadvantage is that everything in the rooms (at least in my room) is designed for persons with a length of maximum 1 meter 90. If you are a bit taller than 1 meter 90, like me, you will have to accept that you will have to use e.g. the toilet adjacent to the nice reading/general room instead of the crampy one in your own room. But, apart from that, the hostal is just great for a short stay.
