We stayed four nights at this hostal. The staff (who don't really speak english) were super friendly, often helping us with questions and special requests. Our no-frills room was small but clean and comfortable. The place offers a very light complimentary breakfast (coffee/juice and toast/cereal). Location in old town can't be beat (near train station and public transportation, too). Fair price, though maybe a little high for what you get. Shower was good and lots of hot water.
The drawbacks were that our room was right across the hall from the reception/entry, and adjacent to the common area kitchen where breakfast was served, so noisy when people were coming and going (though quiet during the night; no ear plugs necessary). We could also hear the water drains any time the rooms above us used the toilet sink or shower. Fortunately we had an interior room; i think an exterior room might have been just as noisy with the busy street location (not traffic but people). The room, while clean and comfortably, had a broken nightstand.
The odd thing was that you always left your key with reception when you went out, and then you needed to be buzzed in the front door to return. Plus the hostal is on the second floor, up a light of stairs with no elevator (that we could see anyway).
Not bad if you're not looking for anything fancy.More
