I spent one week at Bogdanka's apartment. We had an excellent online communication, and I hope next time we will have a chance to meet in person.
The location is very convenient - walking distance to the train station and all the major meeting buildings; easy access to the old town via tram/bus or by foot along the lake.
The apartment is very clean, spacious and has everything for a long or a short stay with a fully equipped kitchen, soaking tub, and a washer and dryer. The bed is comfortable but it's facing a window without dark curtains and in case you have light sensitivity it might be an issue.
One thing that startled me is the acoustics - you can hear when people are walking upstairs and it felt like they are in your apartment hallway. The same, when I walked in the hallway the parquet floor was so squeaky, I was afraid to make too much noise at nigh. Just a funny observation.
Next time in Geneva I'll be staying at Bogdanka's apartment again and hopefully I will have more time to have breakfast at the balcony and enjoy the city.
