Nicely appointed, comfortable and surprisingly spacious apartment in a very good location. Multiple shops, bars and eating places within a few minutes' walk, but the apartment is very quiet - the unusually warm October weather enabled us to sit outside on the balcony with coffee and pastries, and it was very pleasant.
The accommodation is only about 30 minutes' walk from the centre of Paris, and there's also a choice of metro lines (metro from Gare du Nord plus a short walk at the end takes less than half an hour).
Aladin looked after us well - very friendly.
One word of warning: make sure you are familiar with how to get into the apartment building before you go out for the night. We fumbled around for 5 minutes in the dark trying to push open an external door which we eventually realised (in spite of the absence of a handle) had to be pulled!
