The plus sides were that the villa is set on beautiful premises, the owners were very friendly and hospitable, the bed was comfortable (very important) and the property itself was spacious. The location is handy for many different types of day trip (beach, villages, national park, etc). The pool is a wonderful addition and we were the only ones using it in the evenings, so it felt like a private pool, which you can walk out to from the patio: this was amazing.
As other people have mentioned, there were sounds of dogs (and other animals) and there were a couple of occasions during the week when it bothered me a little (i.e. it started too early in the morning or finished too late at night). However, I think that such sounds are to be expected if you choose to stay on a farm in the countryside and it certainly wouldn't stop me from staying here again. My only recommendation to the owners would be to put some more equipment in the kitchen - I would have appreciated some sharper knives, wooden spoons, small saucepans and (being English!), a kettle. I think these small changes would turn it into a five-star rental.
Overall, we had a wonderful time here and I would highly recommend it to others.
