Stayed for 5 months
Positive note : Blueground has been extremely friendly, helpful, and responsive throughout our stay. The apartment was perfectly clean, clean bed sheets, bathroom linen, kitchen utilities, etc.
Points of improvement : some of the pictures did not match the apartment, for example the bathroom picture on the listing page does not show a big tube passing through the bathroom. They said it's because it was recently renovated but if that is the case then much more needs to be invested in in every room of the apartment (AND add more recent photos). The kitchen only has one hob so only possible to cook one disk at a time which was not very ideal plus there was no kitchen hood so had to cook with the window open at all times.
Anyways, our stay went well, very nice area, never seen a mouse or rat in the building (very surprising in Paris), and again great service from Blueground and would definitely book through them again : )
