Okay, so the Hilton is never going to be a dive or really bad. I stay at the chain's hotel regularly.

The Berlin Hilton has a top location but the inside disappoints. Lobby, restaurant, room all smacked of early nineties design and certain budgetary constraints.

Breakfast was included in my room rate, but I would have been very sour had they made me pay EUR 25 for what was on offer. Nothing more than standard. Not one bit.

WiFi in room EUR 22 per day, come on guys, get real.

All in all, there are better deals in Berlin.

My husband and I stayed here on a mini-break to the city, thanks to a bargain airline and an even better 'top secret' deal on the hotel.
The Berlin Hilton is in a perfect location for Checkpoint Charlie and all the sights, and has the Stadtmitte metro station right outside. The two cathedrals outside in the square are beautiful, and I'm sure the place comes alive with music and beer in the summer (we stayed at the beginning of March so slightly chilly for as fresco dining!).
As you'd expect from a hilton, it was spotless and with all the nice little extras which come as standard. With a room only deal, we chose not to pay for breakfast which was around 20 euros, but there are plenty of places to eat nearby - including the cheesily named Snackpoint Charlie.
The pool and spa is also gorgeous, and the perfect way to unwind after pounding the streets sightseeing.

Excellent 4 day stay at the Hilton in Berlin with good bedroom - clean and large room, twin beds, perfect floor and quiet
Pool - perfect temperature and size
Staff - attentive
Location to city centre - perfect
Trasport - perfect with an underground just outside the hotel
Food - not so good - we got a bad deal for the £50 meal we had in the Hotel Restaurant, mine was the vegeterian option, so tiny, that it could have passed for a snack!
Train to Airport no problem.
Lots of good museums and shops nearby

We are staying at Hilton Luxembourg (another story) and planned a 3-day visit to Berlin while in the area, only checking-out this morning! We were lucky enough to choose the weekend commemorating the 60th anniversary of the Federation of the Republic of Germany (23/24 May) and enjoyed the festive atmosphere. We were upgraded through HHonors to a corner junior suiite - 4096 - which offered close-up views of the beautiful French and German cathedrals in Gendarmenmarkt. The suite was approx. 8m x 7m and comprised an entrance hall, a lovely sitting room with three floor-to-ceiling windows, a sofa and 2 armchairs, a huge LCD tv and a business desk etc. An opulent double-handbasin, black granite with white tiled bathroom provided all the amenities and a nicely-proportioned bedroom with another LCD tv with lots of wardrobe space and drawers. The executive lounge was on the 6th floor and was very pleasant with some comfortable sofas and plenty of small tables and chairs set in groups of 2 or 3.There is a help-yourself system to the drinks, which was very generous and the food was plentiful and varied. The only downside was a very young child whose parents were determined to enjoy their drinks even though their son was running around screaming, quite obviously very tired and needing to sleep, so they half-heartedly took him out into the hallway but brought him back moments later. This detracted from the pleasant surroundings until they eventually gave up! Breakfast in this lounge was also more than adequate with choices to suit everyone, hot and cold, healthy and slightly less healthy! Staff were all very helpful and seemed to know the answer to any question! We did two of the Berlin Walks and would highly recommend them, "Discover Berlin" and "Potsdam". The hotel is within a short walk of Checkpoint Charlie, Brandenburg Gate etc. and Unter den Linden is a beautiful area to walk around only minutes away. Buy a Berlin Welcome Card at the airport as it covers all transport systems and savings on many attraction charges. Incidentally, the train, subway and bus systems are to die for! I am sure they are the envy of most big cities, very efficient and frequent. This city has not given itself over to the car, thank goodness. Can't wait for another chance to visit Berlin and to stay at the Hilton.
