Our experience was ok. Paris great but this flat was way too small for us (me partner and 5+10 year old). Can't see how 5 Adults could fit with luggage, food storage etc.
the weather was excruciatingly hot and the flat did t really prove much of a comfort. Our kids couldn't say boo in the courtyard, when people would tell them to be quiet. The flat is very cute and unique and well located but really only suited to 3 people at best.
