Mark's place is lovely. Located in a new and very quiet area but still walking distance to the central train station and to city centre (10/15min).
The studio is well designed and Mark provided us with two bottle of wine and refreshments. There is a coffee machine, kettle for tea and a microwave. The bedroom is on a mezzanine with very comfortable bed mattress. The studio is on the ground floor with entrance door directly in the street bit that is common in Amsterdam and not an issue a lot given the area.
Mark recommended us places around the studio, activities in Amsterdam and contacted us during our stay to make sure everything was fine. The perfect host :)
