I had the pleasure of staying at Marc's for a long weekend and couldn't possibly recommend him enough.
Marc was a very welcoming and thoughtful host; he provided tips on the city, nice breakfasts ( a pleasant surprise for an Airbnb! ) and overall it was lovely to chat with him - you can definitely tell this is a passion project for him and it's not just about "renting out a room".
The property itself is tastefully decorated and very central with all the main attractions being within walking distance; the room was big (with ensuite bathroom) bright and clean.
