We had a fantastic holiday in Amsterdam staying at Carolien's apartment, just as described and the perfect location.
The apartment is located two minutes walk from the nearest metro station, which is four stops to the city centre of Amsterdam - super convenient, safe, cheap and about a 5 min journey.
We were welcomed by Patrick, given the keys to the apartment and shown around the home - he was also full of useful tips and information.
We would definitely love to stay at Carolien's home in the future. It was a pleasure to come back to the apartment after a busy day exploring :)
