The staff were very friendly and helpful. The rooms are bijou, and have a fascinating layout of having the sink of the bathroom in the room itself, with a modesty curtain you can pull around if you so choose. I have to say I'm not convinced by the "city view" of my balcony, but it was fun to be able to peer down over the outdoor eating area and see all my fellow residents as all balconies face into the same sheltered courtyard area.
The pool and sauna are lovely, though the water was a little chill, but given it was 30 degrees when I went, I can't complain. There is a little gym with bikes and a rowing machine.
I didn't have any meals at the property so cannot comment on that, but the bar was well stocked and had a relaxed atmosphere.
Overall this is a nice oasis in north Paris, well served for public transport by being near Gare Du Nord and Gare De L'Est and a few different metro lines.
Would stay again, but perhaps wouldn't spring the extra for the balcony!
