An amazing, relaxing, peaceful place. Sistema is a wonderful duplex house (two beds, two baths as described). The building and development are recently constructed and we found everything in the house to work just fine. It has a full kitchen (though notably no microwave, but this wasnt a problem for us). The development it is in seems new, and is beautiful with a great pool facility and sauna/steamroom - all with amazing views over the lake. There was also very ample privacy.
The best thing, by far about this place though, is the view. It is just as good, or better than as described in the photos. If you're looking for a peaceful, relaxing retreat while also wanting to experience the Italian lakes, look no further. During our time here, we also drove to Lake Garda and Lake Como, which are about 1.5 hours drive away in opposite directions. Nearby to the house, there are also quaint towns on Lago D'Iseo just a few minutes drive down the mountain - and be sure to check out the restaurant in Paranzica, "Agriturismo" which has great food, friendly service, and beautiful views over the lake.
Highly recommend booking Sistema.
