2 adults stayed at Rotary for 1 night in early Jan 2013.
We found the hotel to be of an excellent standard and extremely conveniently located. We took a train from Geneva airport to Geneva main train station (5 min train ride). Note train ride from the airport to the Main train station is FREE (just get a free ticket from the machine at the Arrival hall). The hotel is literally 5 min walk from the Main train station following Rue Mont Blank until it crosses Rue Cendrier. I had a suitcase with me and it was easy to roll it all the way to hotel. Geneva is different to other cities where a close proximity to a central train station is associated with an 'undesirable' location full of rubbish, drunks, drug addicts and homeless 'elements'. Geneva is relatively small city where everything (at least in the city centre including train station) is very close. Clean, quiet and pleasant location of the hotel also benefits from 3 min walk to the lake and if you cross the lake to the 'old' part of Geneva, you will find plenty of shopping, restaurants and historical sites in a very close proximity from each other.
The quality of the hotel room was very good - looked recently renovated, spacious (unlike Paris city hotels if you have experience to compare), comfy bed with good quality bed linen and beautiful bathroom with marble finishes. Buffet breakfast was impressive with large selection of meats, cheeses, fruits, yogurts, baked pastries, eggs, juices, etc. Front desk service was excellent and very helpful with all typical touristy questions like directions, shops, restaurants etc. Needless to say that Swiss working in tourist industry are fluent in 4 to 5 languages :) Impressive above all! Overall we had a very positive impression about the hotel and i would definitely recommend it for a stay in Geneva.
