We booked a cheap deal to Paris, travelling on Eurostar and were pleased it included a Best Western Hotel and was only a couple of stops on the metro from Gare du Nord. The hotel didn't disappoint. Clean, adequately sized rooms ('spacious' for Paris) and a nice breakfast in a small dining room.
Above all, the front of house staff deserve a special mention. Valentine for booking tickets for Sainte Chapelle and graciously answering all of our questions. Cederic for his dining recommendations (we only managed to get to one of them, but it was excellent), his charm and his sense of humour. He couldn't have been more helpful.
I write this review without revisiting others' comments. Firstly, a lesson learnt - always research neighbourhoods and check out Tripadvisor before 'signing on the dotted line' i.e. if I'd read the reviews first, I wouldn't have booked this trip:
Chateau Rouge is an impoverished area and we had the impression that people were struggling to make ends meet. There were many men selling sweet corn from barbecues made from supermarket trollies, watches , handbags, hairpieces etc which were portable enough to be moved when the police arrive.
Generally, there were many many people on the streets, throughout the day and night. Young men sitting in rows in doorways (i.e. suggestive of homelessness), and those clearly homeless (e.g. sleeping on mattresses on the street). Numerous prostitutes, standing not just by the Afro hairdressers, nailbars etc, but by the supermarket, suitcase shops etc.
The daily street market near the metro entrance rendered the stairway treacherous due to the amount of litter (cleared daily).
I should add that we didn't have any trouble, just felt wary and reluctant to spend any time in the area. We're sorry that we are unlikely to be returning to Best Western Sacre Coeur, and even sorrier that we won't experience again the excellent service provided by their staff less
