We (2 adults and 2 girls aged 8 and 11) have just spend 5 nights in Stellas lovely apartment. Everything is exactely as described and showed on the photos. The apartment is located in a quiet street in a very safe neighbourhood. The girls loved the "upstairs" bed!
We didn´t meet Stella personally, but recieved lots of informations before arrival conserning how to get there, tips about where to eat and where to buy the best food. The info was very good and helpful.
We arrived at Charles de Gaulle airport and took the train directely to the Port Royal station - from there it´s only a 10 minutes walk to the apartment. Stella had recomended a small Italian restaurant almost beside the apartment, where we went the first evening and it was brilliant. The small marked street Rue Mouffetard is also near by and is quite recommendable if you want to buy french specialities and feel a special atmosphere!
All in all: We would recommend this apartment if you want to stay in a very "authentic parisian" area. We would love to come back!
