We had a great stay at Martin's studio this weekend. The place is literally at the heart of the city, in de wallen (red light area) there are tons of bars pubs and shops around you. Plus you could actually walk to places like Jordaan, Leidesplein, de pijp or central station, so this is a perfect location.
The place is just like in the pictures, we were 3 people and we easily stayed there comfortably. The most important thing about the studio is the terrace i guess, which is a lifesaver and probably where you will spend most of your time if you are a smoker. Remember most of the places will not allow you to smoke anywhere in their apartments. There is a nice seating area with wooden floor and a big umbrella in case of rain in the terrace.
The building is a 4 story one and you are at the top floor, Martin and his family lives downstairs, who are the nicest people. Martin will help you with anything basicly, just ask him if you need anything or have questions about the area, you will not regret staying at his place!
