We had a nice stay at Gerard's appartment, it is perfect for a couple. He was a great host, flexible with the check-in and came to pick us up at the train station.
He was very friendly and helpful with some useful tips about the city.
The flat is well located, one train station from Amsterdam Centraal (5min on foot + 5min train), very close to the tramway station or about 30min on foot.
The flat was nice, clean, bright, and well equiped but be aware that it is on the ground floor. It is a safe area with a lot of shops and supermarkets nearby.
We highly recommend this place for a stay in Amsterdam!
