Jo's place was a perfect place to stay for our night in Cromwell. It is very cute and you can easily feel the history of this cottage. While older, this place had all the amenities we needed and I would be happy to stay again. My group had 4 adults, and while the second bedroom is small, it was plenty comfortable (especially after a few glasses of wine!)
As for location, it is close to the city center and wineries, and we walked everywhere once we arrived.
Overall a great, charming cottage to spend a night in and I will definitely sta again the next time I am in town.
