Loved this hotel. The staff really are great, all of them, which I can rarely say about hotels. By the station, 2 mins walk, trains do run all night but the windows kept most of the noise out such that I didn't have trouble sleeping. Good sized and bright room with decent bed. Pillows rather flat, but normal for Switz, always bring my own. Cover on bed could have been bigger. Internet easy to use, plenty of TV channels. Bathroom clean and bright, big shower with doors to keep water in. Housekeeping observed my 'Do not disturb' sign, which I really appreciate, and were available if I needed another towel etc.
Breakfast was a lovely typical Swiss style buffet which was kept stocked up until end of service. Was welcomed each morning by the staff and did not feel rushed to finish when closing time came.
This is the first time I have stayed in Olten but am glad I chose this hotel. All in all I had a very pleasant stay. The staff here really add a lot to the welcoming feel of the hotel and should I stay in this area again I shall definitely be back to Hotel Amaris.
