I was in Rafaela guest house on week, in single room. It is simple, and it is good price. It is exactly that what is written in Malenas information about room.
Bathroom is shared between two rooms, but I never had problem with that, people take care of each other here, so don't worry. Same is with kitchen and daily room. On the top of building is great terrace, you can enjoy breeze when you feel is too hot to be inside, cause single rooms window is not towards the street.
Street is quite, is just used by people who live there. Few minutes from house are two supermarkets, and small shop is just on other side of street if you need water or paper. Next street are filled with shops, and small places where you can eat variety of small dishes, together with locals.
You can borrow bikes from house,I like that. it makes easy moving around town, don't be scared of traffic. Small bike lanes can take you all way to Alcasaba or to the beach or longer to Sports hall and Estadio Ciuadad.
But look around when you biking, some pedestrians somehow prefer to move over bike lane without looking over shoulder first!
Hope you will enjoy your stay like I did, and be prepared, Malaga can be real hot place! But there are many beautiful parks in town to make a break. Cheers!
