Christa and Zach's house is a great option for those who are on a buget and still want a nice room, placed a good location. It is close to a station (10 min walking distance), there are many delis and good restaurants around.
Communication was always very fast and clear, they are great hosts, provided all the information we needed, regarding the house, neighborhood and how to get to their place from the airport.
Although our room was a little bit tinny, it was pretty comfortable, clean and met our needs.
I definitely recommed their place. :)
