Mark is the perfect host - super friendly, attentive, flexible, and easy going. An earlier check in wasn't a problem, the bottle of wine he gave us as a welcome gift was really delicious and he even offered to make us coffee before we left. Also he provided us with some great tips to explore the surroundings, which are rather nice as well (just check out tHUIS aan de AMSTEL for breakfast before heading for a walk to the city center - Mark will tell you the best way to get there).
The apartment is very nice and cozy. There is no traffic anywhere around so it's also quite and it has a nice view - perfect for a romantic getaway.
