Charles' flat is comfortable and spacious and everything is there to make your stay pleasant. The bed is comfortable, the TV and wifi work perfectly, and the area is a safe and comfortable neighborhood. Checking in and out was staight forward.
Although it is a few tram stops from the center of town, that never bothered us. The area has everything you need at the end of the day, is quiet, has a lovely park, and Paul's Burgers, right near the tram stop, was fantastic.
We would absolutely stay there again if we ever are back in Amsterdam.
