This is a great choice for a single or a couple visiting Lyon or for working at the ENS the Lyon for a short period of time. This is a cosy, very clean, comfortable, and quiet place close to the ENS de Lyon and only a short ride on the tram or metro (the stations are really just round a couple of corners) into the center of Lyon. It has bakeries, supermarkets and a few bars and restaurants (e.g. JOLS) in close vicinity. Sonia is an excellent host who warmly welcomed me when I arrived, gave good advice, adds personal touches (the flat had a few subtle touches inspiring a Christmas mood when I arrived, and I quite liked that), and responded very quickly to the one query I had despite the fact that she has a very busy professional life (and can be without internet access for periods of time). Lyon is worth a visit - I did explore a few of the many excellent restaurants on some of the evenings, and the Musee the Beaux Arts had an excellent exhibition on "Los Modernos" on - and Sonia's place is a good choice for visitors.
