This was the perfect place for me and my 4-year old daughter during our three night stay.
I chose a hotel rather than an apartment for the social interaction. We saw lots of Pauline and Luco in the communal area, who are such a lovely couple and were very patient with my curious and inquisitive daughter, and met many of the guests, which I really enjoyed and was great to improve our french! Breakfast was perfect and it was great to have a kitchen to cook our dinner as its not always practical going out in the evening with a little one.
The location is great - not too far from Gare du Nord if you get the Eurostar - and close to the sights of Montmatre. Although just off a main road, it wasn't too noisy and felt fairly tranquil once inside.
I would definitely come again and highly recommend it!
