We had a pleasant stay in Bologna with friendly Gabriele. He was very responsive and accommodating. We had a car so having our own key to open the outside gate and a safe place to park was great.
There are several supermarkets, restaurants, bakeries and cafés within easy walking distance. The kitchen had all the necessary amenities, including some delicious olive oil. The fridge and washing machine work well and it was a pleasure to be able to cook with gas.
This quiet private basement apartment in a big family house does provide some relief from the heat but when it really gets hot, there's no respite in the form of AC or fans. You just have to open all the little windows to get some air circulation. There are mosquito screens installed in all windows but their fit is not perfect so we got bit a lot. Gabriele does provide mosquito coils but that was not an desirable option for us with small babies.
It's Italy, in a nice quiet neighborhood with a nice shady backyard, so you're just going to get a lot of mosquitoes. Just be prepared.
Since it is a basement, there also is a bit of faint mustiness, some people may be sensitive to that, but with the windows open it dissipated fairly well.
Like another reviewer said, it's not a 5 star hotel, but it's very well priced, has a lot of character with the beautiful murals, Gabriele is very friendly and responsive and it is in a nice quiet neighborhood with safe gated parking. So this is still a great place to stay for many reasons.
