Best described as an army barracks-functional with no frills. Consists of two dormitory style blocks linked by a glass unheated tunnel, not good in minus 1. Rooms are small, clean and warm. Small restaurant, breakfast hardly worth bothering, limited would be a fair description. Evening meal from 1800 is good for the captive audience (hotel is in a fairly basic residential area ie not a cafe in sight). The restaurant is closed in the afternoon so it is not possible to get a coffee or any nourishment (even vending machines are missing) until 1800.
Wireless internet is available for 12 euros a day, 3 days costs 36 euros but 5 days is 29, figure that one out. If everybody stopped staying at these places which rip you off for the internet they would abandon this robbery. Unfortunately I was a late booker and desperate.
The plus side is that the staff throughout are very pleasant, it's a 5 minute walk to the bus stop and then 15 minutes into town.
Conclusion - it's cheap and cheerful or maybe it's just cheap.

I reserved a room at the Ghotel at the last minute when no other hotel in downtown Braunschweig had availability.

The Ghotel is in the Heidberg distrct of Braunschweig (south part). Ghotel is run by Deutsche Post (i.e. the German post office). The miniature soaps & shampoo bottles all have the Deutsche Post logo on it.

I stayed in a single room (50 euros a night from Expedia, although the sign outside the hotel says it may be ~45 euros or so. The room was VERY SMALL (or "intimate", in real estate terms). The bed was not much bigger than a couch. One pillow. There was a comforter on the bed and a heavier wool blanket in the hallway closet space. Don't forget to lock your door with your room key if you're inside or out (i.e. the doors don't lock unless you use the key to lock them). The rooms are equipped with direct dial numbers, so people can call in without going through a hotel operator.

The rooms are drafty if there's a breeze outside. You'll hear the whisling of the wind as it blows under the doors and around various places in the building. I stayed here in December and while the heat was turned on in Haus A (the front building), the building where I stayed (Haus B) the radiators were off. At least this December was mild.

As far as I can tell, all rates should include breakfast buffet (although the front office girl - a new hire - made a big deal of checking her notes to see if I was allowed to get the breakfast). There's a little cafe within the hotel where breakfast is served, and they also sell a (very inexpensive) lunch there as well. I didn't try any lunch dishes, but the buffet consisted of sliced meats, cheese, cereal, yogurt (plain), bread rolls, jams & Nutella, coffee & tea, juice & hard boiled eggs. Inexplicably, the cafe closes in the afternoon and isn't open for dinner.

The Dresdenstrasse bus stop is a 2 minute walk away (two bus lines come by regularly, although they stop running around 7 p.m.). The more frequently and later running bus "411" stops at the "Klinikum" bus stop, but that's at least a half KM walk (15 minutes) away.

My impression of it is that it looks like a European dormitory. There are even a few glass fronted (to the hallway) workroom type rooms on the guest floors.

Pros: it seemed really cheap to me.

Cons: it seemed really cheap to me.
