The apartment worked well for us - and is located in a super cozy neighborhood.
We stayed in the apartment with our two 11-year-old girls during a heat wave in Paris - and benefited from the shutters keeping the heat out.
The sofa bed worked fine for our girls, but probably wouldn't be suitable for adults.
Matheus is a very friendly and helpful host.
A few recommendations: had a wonderful breakfast at Cafe Mericourt a few minutes walk from the apartment and a fantastic dinner at Early June by the beautiful Saint Martin canal.
