First, Valérie and Theo were great in communicating with us and gave us great tips on how to get to Paris from the airport and on what to do around the neighborhood.
Sizewise, i would say its currently adequate for two persons. We had our 2 kids but could not fit them both on the sofa-bed, as it is too small even for 2 kids. The sofa-bed is not flat which makes it very unconfortable. I believe the apartment would gain from changing the sofa-bed for a bigger and more confortable one.
Now, what was both the biggest surprise and disappointment is the bathroom. What is surprising to me is not having read any negative comments from prior guests on the poor condition of the bathroom, as it is honestly unhealty. The bath is filty and has many spots of moisture. Taking a bath was not an option and we wore our beach sandals to take a shower. The shower head has a weak debit and cannot be adjusted down, thus i had to hold the shower head during my wife and kids shower for the whole stay.
