We stayed at Emma's studio for 6 nights.
The location is excelent, at a street with many boulangeries and patisseries, 5 minutes walk to metro station and 10 minutes walk to a RER station directly to the airport.
The studio is very small, basic and in need of a renovation, and there is no elevator in the building (4th floor) - but all that was explained to us by Emma before booking.
Emma was very responsive, and replied to our mails within minutes.
She also provided some recommendations for touring Paris, and was very flexible with check in and check out times.
Emma's studio is a great option for the saving tourist. Thanks for having us.
