I stayed at the Van der Valk, Akersloot overnight prior to an all day business meeting the following day. The hotel is beside the A9 motorway, with a motorway exit adjacent and is only 25 minutes by taxi from Schipol. You can get the train from Schipol to Uitgeest (change at Slotterdijk) and then a cab, which is cheaper, but slower.
The hotel is large with the guest rooms all on two floors and connected by a maze of corridors. Everything is well signed but it is still easy to lose your bearings. The rooms are large, clean and comfortable with all the usual extras. I had a room facing the motorway and they must we very well sound proofed, because traffic noise was not a problem.
I enjoyed three meals, one in the restaurant and the other two in the buffet and have no complaints about the quality of the food or service.
There are excellent conference and meeting facilities on the second floor; our gathering had over 150 persons present and the hotel and staff coped well and withour fuss. In fact all the staff I encountered were both helpful and friendly.
This hotel is an excellent alternative to Amsterdam for business, but it is very fundtional and lacks atmosphere which is the only reason why I have only awarded four stars rather than five.
