I had a three night stay at Cristina's apartment. She recieved me very warmly and we had an interesting conversation about lifestyles. She offers her guests a large variety of snacks, coffee, tea etc. and had even bought me some gluten free biscuits!
I think her studio is a good choice over a hostel/hotel in the centre. I liked the local feeling (e.g. chatting with a very friendly neighbor lady!) and the neighborhood in general. The studio is modernly furnished with a fast WIFI and the facilities to do basic cooking. There is very little natural light coming in, though, but since you can spend time on the terrace and the yard and mostly stay in the center anyway it did not matter.
