I would totally recommend this place to anybody visiting Rome. You can get the unique feeling of being in the countryside while instead staying right in the city centre of Rome, in a lively neighborhood. A metro stop is basically on your doorstep and lots of buses are close-by. The house is extremely quiet and doesn't get any noise from the street. The garden is just amazing, it's really hard to get such a green spot in a central location like this one. Clara, the host, a true Roman who can speak both English and Spanish, is really helpful and will assist you with any need you might have, both related to your staying in the house and to amenities around piazza Bologna, or in the rest of the city.

Downsides: if coming during the summer, bring along lots of mosquitoes repellent, as this annoying insect is obviously present among the many plants and trees in the garden. And be careful inside the house if you are taller than 1,70m, as your head might be banging against walls and corners at times :)
