I stayed at the Hotel Universal Pacoche for one night (24 euros for a single room including breakfast). It was a nice hotel, very clean and my room was quiet. There was a TV in the room and wi-fi access. The bathroom was very small but Ok for me. The staff were very friendly and the breakfast (served at the bar next door to the hotel) was good. The location is very close to the centre of Murcia, just over the river from the Cathedral.

Cheap and comfortable hotel near the city-centre (just on the other side of the river), wifi zone available in the hall and television in each room. Hostel price but it was more like a hotel (we paid 28 euros an en suite twin room). It is easy to find, it has the biggest hotel sign I've ever seen :)

Only twin beds available. Bad smell from bathroom, which got so bad I refused to use it in the morning to shower, as felt I would come out dirtier than I went it. Noisy. Good location and if on tight budget stay 1 night only.
