It is a hostel, you might enjoy it!
It is a hostel. Bunk beds with foam mattresses, not fancy, but at $22 a night for 2 people, a good value.
We ended up here for a couple days when the lovely Posada de las Monjas had no record of an internet reservation. And I was very grateful to find the place. Gigi was very helpful, she let us use the internet gratis. She was out much of the day, it was pretty quiet. There is a kitchen, so you can make breakfast, lunch and dinner there if you like. Location is about a 5-10 minute walk from the center, and the neighborhood is semi-industrial, but if you are looking for a safe and inexpensive place to stay try it.
