I recently stayed at the ACHAT during the European Triathlon Championships in Wiesbaden. I booked a business special room on my own thinking it would be more than big enough for me and a bike. The room was very small and I almost couldn't fit myself and luggage in it, I don't think 2 people could stay in a similar room for more than one night with going mad.
Apart from the tiny rooms the staff were helpful and the hotel well placed. The parking cost 15 Euro a day but that is much less than the 25 Euro charged at the Radisson Blu where my friends were staying.
