Our family of 9 just stayed at this property for 10 days. We were amazed at how our large group easily fit into this space - three couples had their own rooms, and three "kids" fit into the two remaining rooms with 2 boys in one, and 1 girl in the other. The bathroom arrangements worked well, because the three toilets and two showers are split between 4 different rooms, everyone could access a bathroom when needed - shocking with 9 people.
We ate breakfast at the apartment each morning and a few dinners as well. We found all the equipment we needed, and all the staples as well (like oil, sugar, salt, etc). The host also thoughtfully left us a bottle of wine which we very much enjoyed!
The apartment is on what is essentially the 6th floor - a long walk up! But the elevator, though small, was very fast and we used it a lot.
There is no air conditioning (typical in Paris!) and it did get warm towards the end of our stay. The apartment has several fans which helped a great deal! The only negative we experienced was that in leaving windows open to get cool night air, we discovered that Paris has nasty mosquitos! We ended up getting bug spray to reduce the biting.
The location is wonderful. A very short walk to the nearest Metro (Poissonaire). Beware that during rush hour the trains are PACKED and since there is no transfer at this stop, you will end up just needing to push on if there is a square inch of space. Fortunately, the trains come constantly, so you can let a couple go by until it looks a little better. Also, walk down to the end of the platform and try for the first car. And it's just a few blocks to Gare Nord, where you can also catch several other metro lines.
The host suggests several restaurant options. And the best part of my day was the morning pastry run and getting a cup of cafe creme for myself :) There is a delightful fromagerie nearby (Ferdinands) who was SO helpful and friendly in helping us pick out cheeses!
The host was very helpful in our planning and so welcoming when we arrived. Our whole family would highly recommend this property!!
