Karim's studio was ideally located in 10 min walk from the place of my meetings. In addition, La Muette is just a block away and there are many shops, bars, restaurants in that area.
The room is quite small but the cost vs quality ratio is ok. It was very clean and for the trip like mine, when you are out all day and only need a bed to sleep and a shower with hot water, that was ok. It has a hairdryer, iron, coffee machine, small frigo, a cooker and a sink. Wifi was a bit slow and stopped working twice, but Karim responded quickly on both instances when I alerted him to the problem and fixed it right away.
It should be noted that the room is on the 5th floor of a building without elevator. So you will get a free work-out going up and down as a bonus!
Karim allowed for earlier check-in and it was much appreciated.
