This is a stylish apartment in a beautiful building in a fabulous location. We stayed for three nights with our two kids, who also thought it was fantastic. The light coming in for the long windows in the living room in the morning was just delightful. We were all really comfortable and slept really well - essential after long days pounding the pavements. We walked pretty much everywhere- but there is a metro station literally at the end of the street, and when it was time to go home - the Gare de Nord is less than 10 minutes walk.
There are loads of restaurants around, also bakeries and a small supermarket two minutes walk away. It felt like a nice, safe neighbourhood.
Thomas, the homeowner, kept in touch and was responsive to our messages. He is a very gracious host!
I would thoroughly recommend a stay here. There are four flights of (beautiful) stairs - but I just kept telling myself it was helping me to off-set the bread and the wine. We miss it already.
