Beautiful house, one of the best we've ever stayed on terms of equipment, both for the outside and in the kitchen. There were minor caveats, such as the problems with the boiler and the Sky receiver for the TV, but those were easily overcome with the remote assistance of Dave and Karen who were always available to reply our emails. One major issue which is not their fault but results from the surroundings (from what we were told, it's the combination of large fruit fields and livestock) are the flies. I have never seen so many flies on my life! So, one advice is to take a couple of citronella candles, especially if you plan on doing some barbecues.
The pool is great and the sun cover keeps the water warm and clean.
All summed up, a great choice for a quiet vacation on the Portuguese countryside.
