My room had a strange smell

I had an unrenovated room and the carpet was holding odors, the bedding set was synthetic and very uncomfortable. It was the worst room I had stayed in in The Netherlands. The room size was reasonable and my purpose was to visit an elderly relative so the location was great for me. Located next to a regional shopping mall -- and easy tram access to downtown Den Hague.

We tend to stay here as it is close to elderly relatives and in a convenient place for 'retail therapy'. This time we had booked the culinairy arrangement and were treated to some excellent dinners served by very attentive, but friendly staff.
The breakfast is the best we have had in the many hotels visited in the Netherlands and the staff, especially the gentleman who has been there many years and switches over from one language without any effort into another, is a treasure.
The rooms are being updated bit by bit and we still had an old room. This was tired looking, but knowing that they are being renovated and they were clean, we didn't mind at all.
We hate the single duvet made of man made fibres, far too hot. Although the bed is large, being a single mattress you get bounced around by every turn your sleeping partner makes. We prefer having separate matresses covered by a single sheet. Hopefully, part of the renovation will be an upgrade of the beds.
Overall, a very pleasant experience and I would be more than happy to return.

We stayed there for a couple of days to visit the city of The Hague. The hotel is situated at a small lake and very close to a very nice shopping center, which was open till 9.00 pm in the evening. You jump in the tram to get to the city center of The Hague within 20 minutes. The food that is served in the restaurant deserves a medal. Lots of parking places anywhere for free!!
