Tuscan break in July

We left busy London for a 4 days visit to our little nest in Tuscany. It was nice to see the house, the olive trees, the forest, the vignard dad is building. Nice...and hot. Sad though. It is so beautiful, so different from our daily life in London, so far away from our London routine.
We wish we could finish at least upstairs so we can at least enjoy our short stays.
Main concerns: mosquitoes in summer and holidays.
