I have stayed at Avenir before. I love it. Super friendly staff & an excellent location. I asked for a top floor room with a view & the hotel obliged....the view of Sacre Coeur was absolutely stunning & we had a cute little balcony with a chair. Double glazed windows cut out all street noise. There was very little noise from within the hotel either. It is easy walking distance from Gare du Nord & a couple of minutes walk to the heart of Montmartre. You can walk to the main shopping streets too. Lots of shops, eateries, bars &, despite being quite near Barbes Rochechouart, it is not a seedy area at all, we felt completely safe & comfortable. Our twin room was warm & clean, the beds were comfy and our bathroom looked to have been recently updated & with a very nice hot shower. Towels & bedding were good. This is a typical Parisian hotel, no frills but decent, safe, excellent value accommodation. We did not have breakfast in the hotel, got up too late... but there are loads of cafes around. Special mention goes to the reception and cleaning staff..all were friendly, smiling and welcoming..extra thanks to the lovely lady for chilling our Prosecco in the fridge!! We will stay here again when we visit Paris.
