I've never been in Mannheim before so it was not easy to find the right place. I finally followed the other recommendations and I was really happy with my choice.
I booked directly in this hotel and the owner was very friendly, asked for my room preferences and I could see the room on their website which gave me a good fist impression.
Arrived there, I was really tired and their helped me with a parking lot directly in front of the entrance door (the owner removed his car and provided me with a parking allowance which is needed in this area) - this was so great as I was travelling through Germany and carried so many things with me.
Someone helped me with the luggage and I got the key and he helped me to the room.
The room was lovely, small but with an average size compared to other city hotels build in the 60ies, the bathroom was very nice, with a shower cabin, very good choice of toiletries and this kind of old fashioned towels I love where the hotel name is woven into the towel. My impression was that these small things are making the difference!
The hotel was quiet (imagine the main station is 300 m away!) and I felt very safe there. The door was doubled so I didn't hear any neighbors.
The bedding was excellent and I slept very well.
The breakfast was in a cosy breakfast room with a very good choice of things. I was glad to see that the owner's family is there and everybody really cares for the guests. I was highly impressed because of that too.
W-Lan worked perfectly and I could prepare myself for my meetings the next day.
Shopping in Mannheim is a pleasure (I wasn't aware of this before) and you can reach all these places by a short walk.
One last thing: the minibar is filled with non-alcoholic beverages for a very reasonable price (each item was charged with 0.50 or 0.60 EUro only). You can also by beverages directly at the reception desk. I wish this could be a good example for other hotels as well!

I reserved Hotel Wergener because Mannheim is near from FRA airport (only 30 minutes by ICE) and Hotel Wergener is only 200m from Mannheim Hbf. Outside view, public area, and most room facilities are average of 3star hotel, and in average of Germany hotel, clean in spotless. The room has huge basin, and in minibar, one mineral water bottle costs only 0.5EUR. Special feature is excellent breakfast. Of course there is no selection of egg cooking, but there are over 20 selections of sausages and bakery. I have never seen such great selections.
The hotel has no A/C. In spite of near location from Hbf and main street, surrounding area is quiet, and I could sleep well with open window.
I highly recommend this hotel in Mannheim.

I made my reservation by phone after visiting the hotel website, mostly based on the excellent location just a few steps from the main railway station. (I was arriving by train from Frankfurt airport.) When I arrived, I was a little worried at first, because the hotel doesn't look very nice from the outside and the front desk area as well as the internal hallways look very old-fashioned.
My room was nicely furnished and in excellent condition though. The bathroom/shower was very nice and clean as well. It seems that the rooms have been refurbished just recently.
Nice surprise: the stuff in the minibar was very inexpensive - the price for the mineral water was less than what I paid at a shop in the railway station!
The room rate (incl. breakfast) was €62 on a weekend, which I found good value, considering the size and quality of the room. Unfortunately I slept too long to enjoy the breakfast, so no comment on that.
The one thing I didn't like, was that VISA is the only credit card accepted. Therefore I had to pay cash because I have MasterCard and Amex only.

My husband and I spent 3 nights at the Wegener during September 2004.....and had a wonderful stay! Nice CLEAN, nicely furnished, rooms; a variety of sizes and accommodations; excellent showers and baths; wonderful helpful staff; awesome fresh breakfast buffet, included in the room rate; convenient to downtown area, train and tram stations. The next time in Mannheim, we will definitely return to the Wegener! A HIDDEN TREASURE!!!!!!!!!
