The location of this flat is pretty awesome, and we found it to be well equipped with everything needed for our stay. When we had a question, Flo was quick to respond. We appreciated having a nice clothing washer and nice drying rack, but could really have used an iron. The kitchen was great. The only drawbacks were the noise level in the alleyway at night, and we felt that there might be some mold issues in the building which were affecting the sinuses. However, we understand the building is old and that is not the direct fault of the owner. Also of note, if traveling by foot from gare du nord it is not too expensive to take an uber (I believe it was 13 euro) so that you don't need to pull your luggage uphill, for those that may have problems doing so.
