Definitely not the nicest place in the world, but an ok stay for a night or two (like others have said here).
I’d definitely say this place was kind of like a bachelor pad, very minimal decor and no light fixtures (light bulbs dangle from the ceilings). It also smelled a bit musty. It was very spacious though and in a great location, so those were both plusses.
Considering the price in Geneva, you’re getting about what you’re paying for for a large private apartment.
