Joao's cosy apartment in the heart of Geneva makes a great base for a week or so. For self-caterers there are two supermarkets in super easy reach, and there's always the Migros at Cornavin after hours, about ten minutes away. For those less inclined to cater (!) there are restaurants galore within easy reach. For those who have to work (sigh), pretty well everywhere's in easy reach either on foot or by tram. Definitely a good spot for a base.
