I say "long-stay hotel" because it has all the hallmarks of it. We had an apartment with a separate bedroom (twin beds), living-dining room, well-equipped kitchen with dishwasher and washroom with separate toilet, and lots of storage space. High ceilings, wood floors and large windows made it very comfortable. But, this isn't a full-service hotel - please realize this before you make a reservation. If you come for more than a couple days, maid service is once a week only (good if you don't want to be bothered), and there is no room service is minimal. But you can cook your own meals, which is useful, and the location is perfect. The one thing I didn't like is the bedding, which seems to be common in Accor hotels: there is no sheet, just the duvet in its cover. But some people like it, it would seem! Also, the wireless Internet is too slow, but it is included and the connection is reliable.

I stayed at this hotel in March 2009 and was favorably impressed at the time. Especially its central location and the kitchen facilities were seen as a plus. Since I come to Strasbourg regularly for work I decided to book again for October 2009. Then, I too experienced being bumped out at one week's notice due to someone more important wishing to extend a stay. My booking had been made 7 months in advance. The proposed alternative was somewhere far away from the center with no transport links so I was 'offered' a taxi in for the morning and out for the evening. Not much help with irregular working hours and the need to eat since it had no kitchen facilities.
I'm afraid that I would not recommend this hotel since canceling long-term bookings at the last minute without providing an acceptable replacement room is a totally unacceptable way to run a hotel when one is a business traveler.

I stayed in this residence once in 2008 and in Feb. 2009. I travel regularly to Strasbourg for work, but was unable to get another reservation until this month and Dec, as it immediately became popular. I was pleased with my previous stays, and staff accommodated my wish to be on the back.
Two weeks before my October reservation I received an email saying that they could not accommodate me in October or December and had made a reservation for me at another hotel. Further communication established that they had extended a block booking and were dislodging 26 persons who already had previous reservations for the months of Oct, Nov, and Dec. The receptionist was completely deaf to my protest that I had made my reservation more than a year in advance, and guaranteed it with my credit card, and therefore the studio was unavailable for them to rent to another party.
In early July 2009 I made 10 reservations with the Adagio in 2010 with their central booking office, but the Strasbourg residence has still to confirm in writing, despite my asking them four different times (they say the reservation is in order, but make excuses each time about the written confirmation). I have written to the manager and am awaiting a reply.

We stayed 10 nights in an apartment at Adagio in Strasbourg and were very pleased. We booked online and there were no problems. The location is excellent and we found our room to be as good as new, well equipped (including kitchen ware) and the staff were very friendly and helpful. Our room did not have much of a view (inside yard), but we weren't expecting it either. If you're a very light sleeper, rooms on the street may have some noise from trams, we barely heard it.

If your looking for an apartment hotel to use a base for exploring Strasbourg and the Alsace region, we can sincerely recommend Adagio based on our experience.
