Best exec. lounges in Europe?

I would very much like to hear which lounges in Europe are rated as being good (and why).

My own knowledge of the different lounges is a bit limited as I haven't been to many of them.

They can be rated 'good' for many reasons : good quality snacks, great variety of snacks, serving wine and spirits, relaxing atmosphere, nice location, nice staff.....

I am aware that this information can be found here and there on FT but some of the information is a bit old ( and lounges change ) and I thought it would be nice to have a new thread concentrating on European properties.

I like the lounge in Hilton Athenee Palace, Bucharest.
It is on the top floor of the old part of the building with a nice view. It also has a balcony.
It has sandwiches and cakes in the afternoon.
It has wine and spirits in the evening.
I did not eat there in the evenings but the canapees looked very nice and they also had some warm food.
The people working there are very nice.
It was nice and quiet when I was there.

I also like the lounge in Hilton Prague Old Town.
Very relaxing and cosy atsmophere.
The people working there are really nice and friendly.
Wine and spirits in the evening, a lot of choices.
The warm food was not to my liking but I am sure that it is fine for others.
Small sandwiches and cakes in the afternoon

I also like the lounge in Hilton Antwerp.
It has nice snacks in the evening.
It has wine in the evening but no spirits as far as I remember.

And I also like the lounge in Hilton Slussen, Stockholm.
It has a very nice view over the city.
It has wine and spirits in the evening.
As far as I remember it has a nice enough choice of snacks in the evening.
I have never seen what they serve in the afternoon.

And I like the lounge in Hilton Vienna Danube.
It has wine and spirits in the evenings.
As far as I remember they served quite a lot of warm food in the evening.
I never saw the afternoon cakes but should be good as it is Vienna.
