We stayed at Dirk's apartment for 5 nights and we spent nice time there. Unfortunately, we didn't met Dirk, but his neighbor handed us the keys. Dirk kept in touch with us before and during our stay. He left us with the very useful notes, which helped us to spend a nice time. The apartment exactly matches the description and photos on the website. The location was great, in a quiet local area, in 5 minutes walk to the closest Tram station (15 min and you are in city center). If you prefer to walk, it will take only 30 minutes to reach the city center. One thing which can scear you a bit for the first time it's the stairs, but the second time it's not scary at all and you will find this so-Amsterdam :)
I almost forgot, dear Dirk thanks a lot for a bottle of wine, it was so hospitably :)
