Kristel and her husband are very kind, they answer all my questions quickly.
The appartement is just look like as shown photos, but it's a basement of Kristel's house (few light and fresh air, much colder than outside, smell musty). Near to transport and supermarket, but you still need at least 30 mins to get to downtown. This basement is not so isolate, I can hear everything upstairs (what they say, when they walk, especially when their children crying and running in the house). For this price, If you don't mind staying in basement and aren't to the noises, it's still a good choice.
