This is a lovely cottage, and the owner is terrific.
We didn't have heat, though, and it was 40-50 F. Owner worked with us (provided wood and showed me how we could do a "boost" of the system, which would turn on the radiators for an hour). I got up through the night to do that, but still was below 60 degrees in the cottage.
Afterwards, I reached out to the management company, they accused me of lying about the heat, that it was working, etc. At least a dozen messages where I was told that I was lying and the heat was working, that I should have contacted them, etc. The owner met us and explained everything to us - we didn't arrive until after 10 pm, so I didn't call the mgmt co.
So, as long as it is nice out, and you don't need anything from the management company, I would say it is a good place to stay. Again, the owner is a lovely man and the cottage is quaint, well kept, and in a good location. Heat, though, was a problem in March, and the response wasn't appropriate.
