I would recommend the house so long as people are aware of a few things.
What was great: the view is beautiful; the master bedroom is comfortable for the most part; it is in a great location being close to Arezzo and Cortona. We had dedicated wifi after a few days. The owner was very responsive to some issues we had.
Things that need attention: the kitchen is not really set up with nice cooking equipment - many of the pots and pans are quite old or nonexistent; we thought we were getting an above ground pool but we got a kiddie pool; the second bedroom is really for kids (beds are small); no cable or satellite; no real living room - large open kitchen.
Also - this is very common (as we found out) but needs to be reiterated - the road to the house is very narrow and is in bad shape. While we were there several rain storms eroded the road even more that is was. Our car was too wide to get to the actual parking spot by the house and it was a bit tricky to park. Just beware.
