The photos showing the hotel are somewhat different to what we experienced.
Pros
Location was good as close to Gare de L'Est and a short walk from Gare du Nord. Concierge staff were friendly and helpful.
Our room was small but practical.
Air-conditioning actually worked.
The bed and bedding were clean and comfortable.
Free Wi-Fi.
Clean towels.
Free tea and coffee in the bedroom.
Cons
The bedroom decor was in need of attention.
The bathroom glass vanity shelf was sloped forward so most items were sliding off. We had to place wet tissue to stop this.
The mirror light didn’t work.
The shower cubicle was very tight given I'm 5'10 and broad upper body.
Breakfast was served in the basement. The space was small with 8 small table with barely enough room to get to the breakfast bar without knocking into someone or something.
The breakfast menu was limited; choice of 2 cereals, sliced brioche, pain aux chocolat and croissants/apple pie, boiled eggs that you had to wait to be cooked in a 6-egg electric cooker, plain/fruit yoghurt, apple/orange juice, coffee machine, selection of teas, jam/honey/Nutella minis, a selection of non-halal meats and cheeses along with butter and finally apples/oranges.
No sauces
Only 1 salt shaker which everyone shared.
Overall, if you're solo or using it just as a base, then you'll be fine. If you're planning on relaxing for several hours without feeling boxed in, might want to consider a larger room than the double room we had.
