I stayed in this hotel for two nights in order to watch the England v Samoa game in Nantes. I now realise it was perhaps not the most convenient location, being a good way out of town. It is pretty near the airport (by taxi - no public transport from the airport) but otherwise is a little 'in the sticks'. However, once you get to the public transport network it is great - cheap, clean, efficient. Check out the TAN website (in French) - parking at the termini is free if you buy a ticket for the trams and you can be in the town centre in 20 mins. Another 25 mins sees you in the stadium at Beaujoire where the rugby takes place.
The hotel itself is your bog-standard chain hotel. The room was clean but basic. The public rooms seemed a little shabby but as I didn't spend much time there this didn't really bother me. When I arrived at the hotel each night the small and rather depressing bar seemed like the twilight zone - everyone seems to have gone to bed, including the staff.
There is a pool, which I didn't get to use.
Breakfasts were OK, nothing to write home about. I did use the restaurant attached to the hotel twice (unfortunately they had the same menu both nights) and it was very good.
