Exceptional

Pleasant

Basic but convenient and friendly...

Liked: Very convenient location a few minutes' stroll from the railway and bus stations in one direction and the cathedral in another. Cute Art Nouveau windows in breakfast room. Room has a useful desk and is basically comfortable. Friendly lady on duty at reception.
Disliked: Bathroom was very cramped. Shower especially difficult to use; it's hard to turn around without knocking the tap and accidentally altering the stream or temperature. Reception hours are quite restricted; arrived at 1pm and, while I didn't expect to be able to enter my room straight away, it would have been great to be able to drop my bag. Breakfast is a bit limited.

Good base to explore Amiens....

Liked: Good location to explore Amiens. Close to the Railway station and the city center. Budget room had everything you need for a place to sleep - bed, toilet, shower. So it was exactly, what I was looking for.
Disliked: As I arrived there was a sign at the door "Hotel closed". I panicked a bit, as I thought, it was closed for summer holiday and that I won't get to my booked and prepaid room. At the end it turned out, that only the Reception was closed, but the hotel was working. With the help of other guests I got in and my room room key, which was labeled with my name at the key board. It would be better, the hotel writes "Reception closed" instead of "Hotel closed" on the door to avoid misunderstandings.
