Me and my partner spent 3 nights at Pascale flat and we did like it. It made our stay in Paris confortable and enjoyable.
It's a very stylish flat: great wooden floor, melange of warm and light colours, nice lighting system, a gourgeous bathroom, confortable futon bed, well equipped kitchen, perfectly working wi-fi, wide tv/dvd system with some dvd available, and perfect heating system (in november it was pretty cold outside). Despite being in a central location, the flat is extremely quite.
Being at the ground floor, it's not very bright and sunny. But this is definetly not a problem when your plan include to spend the day around the city.
It's so central that you don't even need to get the metro to reach most of the best spots of Paris. Anyway, the closest metro stop is just 50mt from the place.
Everything as been very easy: Pascale is very kind and always replyed to our messages and emails very quickly and we didn't have any problem in getting the keys.
I do advise it for your stay in Paris if you are looking for something special
