We enjoyed staying in Cosy Daisy apartment! The location is great, close to the metro station and you can reach Eiffel tower in 20 mins by foot. The apartment was recently renovated, it is slightly smaller than in the photos but it wasn't an issue for us and we've found everything we needed inside. The apartment is very warm and has heating in every room (we've stayed there in mid-October).
It also has a lovely small balcony.
Watch out for the stairs, it might not be suitable for people with the baby stroller or if you have a bulky luggage.
Self check-in is very convenient and Celine was always accessible when we had questions.
