Song's place is really nice, with great views from the 9th floor balcony and in a lively part of Paris. The whole apartment is clean and tidy and there is an amazing music collection to enjoy.
We had initially booked for 8 people but only 5 ended up going, which was a blessing, as although it says it can sleep 8, 3 of those would be sleeping on mattresses on the floor. Also, there is only one shower room and one separate toilet, which opens out onto the communal space which isn't ideal.
If that doesn't bother you then the light airy flat is great for a weekend.
Song's communication was very good, arranging for a neighbour to let us in as he was away.
All in all a great trip and nice place.
