Lovely apartment in the heart of Paris. We stayed for 3 days as a family of 5 adults. Apartment is exactly what you see on the pictures, one bedroom with proper bed for two (comfy), living room with kitchen (spacious enough). Living room has a big sofa, which is converted into a sleeping place for 2 (a bit old but comfy) and a small sofa (sleeping one). Kitchen has everything you need, if you would like to cook.
Apartment is VERY clean, has a lot of amenities (shampoos, conditioner, white fresh towels, clean white hotel like beddings etc.)
Check in / out is very easy.
Host was very sweet, answered all our questions quickly and accurately. Even helped us to find parking nearby. There were Nespresso coffee capsules in the apartment and a complimentary bottle of French wine (thank you!).
Couple of reviews said that it was very very loud outside in the mornings. Apartment is located in the heart of Le Marais, so its natural that cafe downstairs will be busy preparing for the day in the morning. I cannot say that it was too loud! Normal Parisian morning - that's all.
Something to note: the flat was ok for 5 adults, however there are only 4 chairs, so it was not possible to have breakfast all together (someone had to be standing). The sofa bed for 1 person was not very comfy, and small. So, even though it was completely fine for us, this might be an issue for some other visitors.
Overall - we will definitely come back!
