Sarah is an amazing host, she texted me the day before to arrange the best time to check in for both of us and when I actually did, she explained me everything I needed to know about the flat and we also had a lovely conversation.
The flat is really clean and the room is in fact very cozy. With those small Christmas lights and the minimalist deco I felt very cool when in the room ;)
However, I would suggest this place only to people who don't make too much noise during the week because Sarah is a busy woman and needs to get up very early in the morning.
For me, it was the best Airbnb room ever.
