We spent 4 nights at Catherine's studio. She was very nice to us, explained everything in details, in the room, also recommended restaurants and things to visit. She even brought us a small surprise, home made marmalade and verbena liqueur. Both were fantastic :-).
What we can say against the studio is the low internal height, so it's not recommended for basketball players. Otherwise the studio was nice and clean, at a very good location and far away from city noise. Overall we are extremely satisfied and can only recommend this place to stay.
