As a preliminary, this trip was neither business nor leisure. I do wish the travel trade would drop this distinction.
Looking for a stop-over on a drive back from Denmark, I followed the 'hotel route' in Celle, and saw this one near the centre with (free) parking spaces in front.
The hotel was no doubt relatively expensive for Celle but, with 7% VAT, German hotels usually offer value, and this one did. My single room was reasonably-sized, but I would not have chosen it for more than one night, since it was rather stuffy (even though it was not hot outside) and the ersatz-English style does not appeal to me. But the TV had BBC World and TV 5, and there was a safe. The bedlight was only 25W with a thick shade, presumably to make the room 'cosy', but was useless for reading by. On the other hand, the bathroom was very well-lit and modern. The corridors leading to my room were also well-lit. Very odd.
The hotel has a big lounge, also rather gloomy and not much easier to read in. I had expected to eat in town but, as it was wet, I ate in the Italian restaurant, which had tasty food and attentive staff. The breakfast in the main restaurant was stylish and a real pleasure, with rolls, croissants, etc and coffee brought to the table, and a good buffet in addition.
In the (unlikely) event of returning to Celle, I would probably take a 'superior' room. I had been offered one at check-in but it seemed an unnecessary addition.
