I stayed here with my parents for 3 nights. I had to request on very short notice, but Chris was so nice and flexible to accommodate us on such short notice.

Pros: Excellent communication, charming house, nice & lively neighborhood, though located in a quiet street for a nice and quiet sleep. Nice walk to subway with a lo of shops and restaurants. And kudos to Chris for running such an environment-friendly and sustainable house, excellent! Though we met Chris only briefly, he seems very nice and accommodating.

Cons: Not very clean, unfortunately :( To me, this sadly took away a lot from this stay, because cleanliness is the most important to me, so I personally had an issue with that. The table tops etc. were so dusty/dirty, we had to wipe them down twice to even use them, leaving the cloth completely dark. One of the blankets had brown stains, which is especially uncomfortable when there are no duvet-covers. Though I have to say, since I booked on such short notice, Chris wasn't there the day we arrived to prep the room for us, so he had someone else prepping it for him. So he might be more thoughtful himself, but the person cleaning the room was very neglectful.
Also, the bathroom is a very small, especially for 3 people, and there is almost no space to put your toiletries. So I think staying with 2 people is more comfortable. And sleeping on the futon in the living room area is a little noisier than sleeping in the bed room.
And another minor thing: There was milk and cereals there for breakfast, but since the milk was already opened, I didn't dare to drink any, because I've a bad milk trauma :D So maybe a sticker indicating the day opened would be nice :) Also, after reading the description of the Continental Breakfast provided, I kind of expected Chris to stock the breakfast fridge especially for his guests, but we felt like it was just leftovers form the other guests. But again, Chris couldn't be there the day we arrived.

Overall: If the cleaning issue gets resolved, I would stay here again with my boyfriend, for 3 people it was a little small.
