This home is excellent. It is meticulously updated and maintained. It's small, but 10 times better than a hotel room. Even though it is in an urban/suburban neighborhood, there is no road noise at all - just the occasional fog horn. Four good restaurants are a 5-10 minute walk away. It's really just a cool place where people live with lots of things to do and see. The whole area around South Portland did not feel touristy to us at all.
Finally, even though we were pleasantly surprised by everything else, the main reason we picked this house is because it was one of the only houses on the Maine coastline that will allow a stay of less than 1 week. Coming from California, where it's rare for more than 2 or 3 nights to be required, I couldn't believe people put up with almost every owner requiring a full week stay or more. Thank you Patti and Britt!
