Great Hotel very accessible to all of Berlin
The Swiss Hotel in Berlin, located in the Ku'Damm shopping District is a great location. From Tegel International Airport, the X-9 Bus (which cost 2.10 Euro) will take you to the Zoologisches U'Bahn station in 17 minutes. From this U'Bahn station, the Swiss Hotel is a 5 minute walk.
From the Swiss Hotel, you are a 15 minute train ride from key places such as Alexanderplatz, Unter den Linden, Checkpoint Charlie, and the Reichtag. Near the hotel are many restaurants and plenty of Shopping. Also, the History of Berlin museum is a short 5 minute walk.
The hotel is moderately expensive at around $100-$150 Euro/night. But you are greeted with extremely hospitable people. From the bellhop, to the bartender, to the check in staff, everyone who I encountered were very helpful and friendly. There was no attitude.
The gym facility is not that spectacular, just a couple of treadmills, bike and a stair master with 2 free weights (butterfly and press machine). There is a nice sauna which I did not try and the gym is open 24 hours with supervision from 7am to 10pm. No swimming pool.
The breakfast costs $21 Euro/person but the quality of the food is pretty good. Yogurts are excellent; they will cook you an egg poached, etc; waffles; pancakes (even crepes).
The restaurant is good, but the menu is not varied enough.
The room is very comfortable and the cleaning staff are quite friendly too. The interior is modern, clean, and has all the essentials such as iron/iron board, television, mini bar (that costs), safe to hold your passport, and plenty of closet space. The rooms are quite big too.
Unique Quality: The center of the hotel is an empty space that looks down thru glass at the lobby area where many people have coffee in the morning.
The staff: extremely friendly people. They do not give you attitude at all. If it's raining and they see you walking out of the hotel without and umbrella, they will offer you an umbrella.
I will use this hotel again if I go to Berlin again.
