Joanna is a great host who really fast and answered all of my questions.
The flat is very nice, clean, cosy, quite spacious, enough place for 4 or 5 people. Separate rooms for shower and toilet - which is great for a group of people.
There are lots of kitchen utensils and devices. It has everything to have a great stay in Paris.
It is really close to Chateau d'Eau and quite close to Strasbourg Saint Denis metro stations. Lidl is very close, Monoprix, Franprix are within the walking distance.
We had a great time!
Thank you, Joanna and Adele!
