Stephane’s apartment was big and comfortable for three or four persons. Also, it was in front of a subway station and there were two other lines about 5 minutes away. The block has many supermarkets and grocery stores around, even a few cafes.
On top of that, Stephane was really helpful and always in reach when we needed help.
The only downsides are that the stairs are small and steep for dragging luggage (manageable if you do it once or twice) and that the single beds would be better for children than for adults or bigger people. Nevertheless, the place was great :)
