Those renting appartments with Airbnb know - it is always a lottery. If so - I had a winning ticket. Wonderful place, no doubts. To my eye the reality was better than I expected, those pictures on the appt page ain't 100% true - the place is far much better.
First of all - it's a very calm and comfortable place. It's hidden from the street traffic noise, you can work, read, sleep and relax 24x7. From outside the area looks a bit like a movie set. The room itself is very comfy and has almost everything. The airflow is great, you have windows on both sides of the flat, so its always a fresh air inside.
Have a short walk around the block then you find a couple of food stores, laundry facilities, farmacy, and a range of eateries (many!). There're two metro stations nearby - an ultimate option in any city! - a RER B's Port Royal station (which is a direct airport link) and Raspail station(Trocadero/Eiffel Tower area etc). Priceless.
The host was accurate and responsive.
The place has no elevator, be prepared for a short 2nd floor climb. I had no problem with the stairs, just be informed.
My recommendation to the host is to add a big mirror somewhere. It's Paris, people come to dress up and celebrate life there !
Would I recommend this place? Absolutely. Cant wait to get back there.
