Stayed in Annetta's apartment for two weeks with my wife and a 7-years-old son. It is an amazing place to stay! Location is unbeatable. It is equally close to all the most famous and attractive sights in Geneva, and a couple of minutes walk from the bus stop to which the bus brings you from the airport. For those on a budget (like we were) the rather decent and cheap - by Geneva's standards - Coop Restaurant is across the road, as well as the Coop supermarket if you prefer self-catering.
The apartment itself deserves a special mention. Annetta is a really talanted artist and designer. Her paintings are great, and the interior design and decoration makes you feel like the place you live in is a work of art in itself. Awesome!
The only thing I missed was an opportunity to talk to Annetta and get to know her better. Both my and hers working schedules prevented me from seeing her almost complitely. We mostly corresponded via SMS, in cases of necessity (to which she responded promptly and efficiently). Having a chance to interact with her in person would definirely add an extra dimension to our Geneva experience!
