My colleague and I stayed at Mattijs‘ spacious and stylish apartment for almost a week and enjoyed it very much. Check-in was super easy and Mattijs was there to welcome us and even left a bottle of wine and crackers for us to enjoy. Throughout the stay he kept checking via text message if we were ok.
The apartment is situated in a lovely neighborhood that is not as crowded and touristy but still has a lot to offer and is close enough to the city center (walking or by tram).
Just note that the apartment is in a typical Amsterdam house with quite steep stairs and maybe (probably a woman‘s problem) bring an extra towel because there was only one for each of us.
