Clean and comfortable hotel about a 30 minute drive to Cologne, set in a very nice resort-style city. Very quiet area. Room clean, a, bit on the small side, basically one double bed (they do not have twins, so take this into consideration) one desk and one TV. Room cleaned daily, heat was working. Great breakfast everyday, better then the room. Everything in their lobby mini-shop was crazy expensive (think 6 euros for a bottle of water). Decent on-site bar and restaurant. All in all I would come back again.

Front desk a little bit 'cold', thou efficient. Meaning no response to 'hello' or any other interaction during our stay. When asked or engaged, they were courteous. Parking is either paying (hourly, city parking on the street) or you need to pay to the hotel for using their parking, 12 euros/day.

Clean room, and comfortable. Heating worked great. Location was nice, quiet place. Very good breakfast, they really prepared very well. Nice place for small friend gatherings in the lobby. Room serviced daily.

Hotel staff offered very little interaction, but not a big problem obviously, maybe just a cultural thing. The items for sale at reception were overpriced (think 6 euros for a small bottle of water). Room was rather on the small size - only work for two people if they are a couple. No twin bed rooms available. Hotel parking was paying - 12 euros per day. No complimentary drinking water in the room. It's the small things that make a difference...

The hotel is spatious and modern. Good wifi. It was very quiet at night, because the rooms are well isolated: no noise from neighbouring rooms or from outside. The room was clean. Breakfast was generous. Staff was very friendly and a defect in the bathroom was fixed immediately after reporting.

For people who plan to walk the Rheinsteig: it is a bit far from the starting point of the etappe.

Lovely breakfast offering with lots of choice. Very comfortable beds and good cleanliness. Bright bedroom with big windows too. Unfortunately I didnt have an opportunity to use the swimming and spa facilities.

Only thing I didn't like is the interior design/decor. This isn't a big problem for me! But it felt grey and empty in some places, particularly the corridors.

We found the Seminaris to be pleasant, spacious and clean, set out with conference rooms etc there was a good choice of breakfast, car parking both indoors and outside. The room was clean, spacious and comfortable and there is a large garden area.

There was nothing we disliked about the Seminaris

Thanks a lot for a super convenient and comfortable stay! And the understanding and generous cooperation regarding my bicycle. Friendly and quick check-in and check-out. Breakfast was good. Beds very comfrotable. Excellent hygiene and tidiness.

Superb service with friendly staff. We felt very welcomed and enjoyed the variety of lounge areas which are perfect for chilling and having a good time. Breakfast was great - such a range of healthy and tasty food. There is so much to do in the hotel itself, including pool, sauna, table tennis, etc. We would definelty come back

We liked everything.

Good breakfast included Space for bicycles in garage

Key card was hard to use, had to be put in the exact right location. Maybe a technical problem just with our door.

Brilliantly friendly staff, great location, good breakfast option. As a business hotel it offers a big desk to work at which was very convenient.

Overall great place with good facilities, decent breakfast and good rooms. However, the pillows were very very soft, sleeping on them felt like sleeping without a pillow. We were very tired and fell asleep without issue, however, when fully awake the pillows provide no support whatsoever.

Everything was great, quiet and comfortable hotel in beautiful place, especially the breakfast was delicious!
