Stayed in Cyril and Olivia's place for 4 nights. The place looks pretty much like the photos.
The neighborhood was perfect, everything you would want is within 2 blocks. Nearest metro is 1 block away. Super easy to go at from the airport via Aerobus.
The unit is on the 2nd floor (1st floor if in Europe), with a bit worn down stairwell. Everything inside worked well (except the water heater for the first night, which Cyril fixed the next day).
Cyril/Olivia were very easy to communicate with. Very recommendable!
