The hostess is very very nice. My friends and I came to Paris at about 8 am and she came this house in advance. So I want to thank her for the sacrificed sleep time. As for the house, the loft is very cute with a lot of artistic pictures on the wall. Also there are a lot of cultured and dainty furnitures here such as the carpets and cabinets. Particularly worth mentioning is that the kitchen wares are really excellent.
The drawbacks I saw:
1. Too long Wi-Fi password.
2. The single bed might be short to high people (more than 190cm)
3. Downstair sink is too little to me.
In summary, this room is really really an excellent place to spend your holidays. Good location, tasty foods around here, safe, warm, good view plus a very nice and patient hostess. I will be back if I go to Paris again, no other choice!
