Wonderful clean, quaint, historic apartment in an absolutely perfect location in Colmar next to St. Martin, perfect for a family of 4 or 5 -- as long as one of those family members isn't over 6 feet tall (because of the footboards on the beds in both rooms, my 6'4" husband had to sleep out on the futon in the living room). Owners were extremely communicative and check in and check out were easy -- though the instructions on getting to the dedicated parking spot were a bit confusing, which is a very minor issue. My kids loved the kitchen and being able to do the codes for the doors themselves without worrying about a key.
Only other things that folks should be aware of, but would not prevent us from staying here again:
-bathroom in the "master" is extremely small (but perfectly functional). The toilet and bathroom in the hall are larger.
-we never could get the WiFi to work even following the laminated instructions, which was a slight complaint, particularly from my 11 year old
-it is up 2 pretty steep flights of stairs, so probably not suitable for mobility-challenged or older folks
-church bells start at 5 or 6 am, so if you are a light sleeper and that might bother you, be aware of that. We managed and actually enjoyed the proximity of the church.
