Three things that you HAVE TO KNOW:
1. Is really a small apartment, we were 6 people and was impossible to do almost everything, in my opinion is for at maximum 3/4 people.
2. Is really well located, is two steps from the metrò, 10 minutes from Opéra and Montmartre, there is also a supermarket and a pharmacy at two steps.
3. Buy your own toilet paper because there is only one roll.
So if you are less than 4 I really suggest you this place but if you are more DO NOT.
The check in is automatic, the communication with the owner and the host is good!
