it was close to main train station. we could go there in 5 mins by walking
it has many Indian restaurants in close proximity and off course other restaurants as well

rooms were simple but very clean. tarrif was quiet reasonable considering location

breakfast was excellent

since we had to travel a lot every day by train, it was extremly comfortable

the reception clerk is nice.
NO air conditioner.
also there is a eletric fan, the room in the top floor is hot in the summer.
the apparatus which fixed the shower nozzle is broken.
we stay for 3 nights. the night before we check out, one of us found out that the money in her luggage is disappeared.

I stayed only one night, so my experience is limited, but here’s my review-

Good points-
• Friendly and helpful front desk staff.
• Very good breakfast – lots of variety. Even snuck a couple packaged coffee cakes in my luggage to eat later.
• Abundant hot water and good water pressure.
• Hotel is located in a quiet area – not a lot of street noise.
• Located only a few minutes walk from the train station.
• Hotel is in a nice location on a corner.
• They have a good walk-up rate (if there’s no convention in town)
• They’ll arrange tours for you at the desk.

Bad points-
• Only had one pillow and no extra ones in the closet.
• Internet costs three euros per day (works good, though)

We didn't have a reservation and arrived to Frankfurt around midnight. Tried to get into any hotel at that point.
Columbus wasn't fully booked like the first one (don't remember the name), so we get the room.
Pro's-room was overall clean, shower OK, TV and internet connection worked fine, and thing I liked the BEST - breakfast! I would stay in this hotel just for the breakfast, really. Comparing to other places we went in our European journey, Germany is the country where you can actually find great food and enjoy every bite of it. Stuff was very friendly and helpful! Not the most fancy hotel, but wonderful service.
Con's-carpet has stains.
