It was great staying at Adrian’s place. Most train stations are within 10 mins of walking. The place was very peaceful and is at walkable distance to some of the major attractions like Louvre and Palais Garnier. On top of that, the supermarket was just below the building.
It was easy to communicate with him too as he is very responsive.
I recommend trying Cafe Louise and Junk (burger), if you stay at Adrian’s place.
