We were a family of 4 people and we could enjoy an amazing stay in Paris. The my key house was pretty comfortable but I wouldn’t recommend it for more than 2 people because when you open the sofa bed, the space left to move was very little. We didn’t come across many problems, just some with the wi-fi and the already mentioned small space (like the tiny bathroom). As regard the other services, they were all well-functioning, apart the table that was pretty unstable and a wardrobe that was completely missing.
