The flat is very beautiful and homely and just the right size for us - a couple with a 7 year old. It is really well located close to gare du nord but with plenty of lovely spots nearby. We were aware of the 5 floors of stairs and didn’t mind - but it is a lot of stairs if you have difficulty with mobility. All in all a great experience if you want to stay in central Paris and feel like a true Parisian :)
