The mattress is a bit old and uncomfortable, it should be replaced as soon as possible... And we also think free wifi should be offered as well as some basic amenities (hair dryer...).
Appart from that, Claire is a great host. She was really kind despite our late check-in and she let us leave our luggage there until our departure. The appartment couldn't be better located, we had a really good time, and we loved the city so so much. We recommend it!
