Let's start with the good.
SUPERB location, very close to the Geneva Gare station and supported by busstops and shops all around. Also well within walking distance to the Old Town centre. However.......
Let's talk about the bad.
Because it's facing the main street, and on the highest floor, it does get very noisy, even till late and starts again early morning. You'll hear sirens, buses, cars and all manner of vehicles. The lift getting up to the apartment is ridiculously small, and fits at most 2 at a time with little luggage. Be mindful if bringing strollers and you'll have to walk up some stairs first before reaching a floor to take the lift up. Next, the apartment itself. Heating and ventilation is good, toilet/shower area is great but OMG the squeaky floors were TERRIBLE. Each step taken felt like it could wake the 5 floors of neighbours below you. Host will remind you to keep quiet, but we couldn't do that cause we haven't mastered levitation unfortunately. Maybe ninjas could.
