We spent a wonderful week at Colombia's house. The house is exactly as described on the pictures. It is large, in excellent condition and beautifully decorated. A house with a soul. The "garden" (but large enough to be qualified as a Park) is very well maintained.
The property is somewhat remote hence you absolutely need a car, but this was what we were looking for. Lake Iseo is gorgeous with much less mass-tourism than the other lakes of Northern Italy. Lovere is a very neat and charming city, right on the lake 2!: just 5mn drive from the house. It has all facilities required (restaurants, stores, swimming pool, lake promenade pier, etc).

Valentina (Colombia's daughter) has been a wonderful host, kind,
cheerful and helpful. She provided accurate advises to our various requests (Which store is opened on Sunday? Which restaurant she recommends? Etc). She managed an emergency appointment with a local garagist as our car had some issue, drove me there and translated so that we could fix the issue.
A great hospitality in a lovely house. Thanks Valentina!
