The best thing about Maria's apartment is how quiet it is. It's about a 15 minute walk to the central station and is in the student area, so there are quiet a few bars and restaurants near by, but because you are inside a building with an internal courtyard, and you face onto this, you don't hear noise from outside. It is also very clean and nicely maintained - It was Maria's home for a while I believe. There are good bus links to most of the places you want to go, or you can easily walk to the central station to get the metro. Really enjoyed our stay - Maria is welcoming and helpful.
