I was at Olivier's place from Aug 20th to 28th. it is an old building and old unit and is very very small, I think it is great for one person.
the unit is very very clean and comfortable, the location is fantastic, close to nice cafe, restaurants, and metro. The neighborhood is very safe.
I had little problems checking in and getting connected to wi fi , but I got it after a day, which was an inconvenience for me, could not use viber, which was my only way to make a phone call!
other than that every thing was great.
