Nicolas' place has a very good venue. It is near the Gare du Nord bus station and hop on hop off bus. However, take note that the address is not 103 BUT 105 so you won't get lost.
The host doesn't provide towel, but it was written in his instructions.
Follow the instructions of the host regarding the opening of the door so you won't be told off.
Expect that since it is near the main road, there will be noise at night.
