Adam suites is an agency, you have plenty of different persons and never know who is the manager.
First, they never answered to my first message sent some months ago and we haven't heard any info about them before our trip.
Once we were on Amsterdam supposed to take the key in the agency for getting to the apartment, they didn't have the key and we had to wait 2 hours before finding a solution. We have spent the first night in ANOTHER apartment where there was no heat at all. The second day we could get into our booked apartment and then everything was almost all right, the apartment was well located, clean and quiet nice but not enough toilet paper and not even a bottle of water.
We appreciated that the first night was partly refunded.
In conclusion, I would not recommend Adam suites as it's not sharing Airbnb values and a lack of professionalism for an agency.
