Michel is the perfect host, very communicative, accommodating and open to feedback. The apartment is better than the pictures, amazing high ceilings, spacious and bright. The bed is extremely comfortable and Michel provides all necessary amenities.
As other reviews have indicated, spiral staircase wouldn't be ideal for people with mobility issues and the bathroom door is clear glass so potentially not great for groups who don't know each other on that level! But for a couple it's great. Other issue, you can hear everything in the building - the apartment below had a party which woke me up at 4:30am - sound travels so well that I could hear the conversation. But with earplugs this won't be an issue.
Overall a really pleasant and enjoyable stay.
