Overall fantastic.
Location is in the center of Kientzheim, about a 15-minute walk to Kaysersberg and an hour walk to Riquewhir.
Very modern and updated on the inside.
Ground floor: excellent laundry room with washer/dryer.
First floor: 4 bedrooms (one suitable for 3 people and the other 3 suitable for 2 each), one large modern bathroom, one room with a modern shower and double sink, and one with a toilet and sink.
Second floor: bright and airy, large modern kitchen, dining room, and sitting room.
The house does not have a/c but we were there during some pretty warm weather and sleeping at night was fine as the place is very well ventilated, with lots of operable windows.
Owner was extremely friendly and helpful.
No complaints at all. Probably the best VRBO I've ever stayed in.
