I have been there last week of September and I am overall happy with this hotel. Booked a basic double guest room I was given a king executive room.
There is a small lounge that is OK and serves hot canapes in the evening 6.00 to 8.00; they have some alchool; red/white whines, beers.
I had breakfast in the restaurant and it was good, standard Hilton buffet breakfast, decent choice. I also liked the location: served by buses just in front of the hotel and by an underground station couple of blocks away. Kings Cross station is also a short walk down the road.
It is not a luxury properties, but well maintained, works well and in a good location.
