Banna's apartment in Champel was a wonderful place to stay. It is located on the ground floor and has a nice garden, with lots of light entering the apartment during the day. It is very well furnished and cozy, especially now in spring when we can chill and have wine outside as the weather is good.
Banna was kind enough to provide us with everything we needed( towels, hair dryer, etc), and also when we arrived he had bought us complimentary fruits and some food and left it in the kitchen, which was a nice surprise! He lives just next door and is very available for any queries his guests may have.
As to transport, the bus stop for number 3 is situated literally 1min walk from the property, providing direct links to the very city center in more or less a 10min travel.
Overall very well located, practical and suiting everyone coming to Geneva either for leisure or business.
The only small flaw there was was that the apartment was very dusty, and as I have very strong allergies to dust the first few days were a bit difficult to adapt. However, I am sure that if I had talked to Banna about this issue he would have provided a hoover very promptly.
