Lou is an outstanding host. I felt like staying with a friend (the apartment is a 1 bedroom, Lou was staying at a friends place and sometimes working from the apartment during the day - not sure though because I wasn't around during the day. I felt weird about that he gives up his home to have strangers stay there the first day but then realized that Lou doesn't mind at all and just loves hosting people - and he is a great host, too!). He also had some awesome recommendations to see the city off the beaten path and was so warm and friendly at all times! I am hoping to stay at Lou's again.
The flat is not as tidy as in the photos (more lively ;) ) but extremely clean. I kept some fruit in the fridge and helped myself to filtered water and watermelon that Lou offered to me. I took the ferry (very scenic!) or subway to the places I wanted to see (most within 20 to 35 minutes from the doorstep). Very safe and quiet area - I slept like a baby with the window open. There are some great Greek and middle eastern eateries around the apartment.
