We stayed two nights here in July with two young kids (3 and 5). We wanted something in the historic centre so were expecting a very urban and touristy experience. Instead, we arrived at a lovely old building on a charming, narrow, peaceful, cobblestone street, with an adorable authentic trattoria less than 5 paces away (which we did not try). The flat is small, but perfectly adequate for a young family (kids slept on the sofa bed). It is kept immaculately clean, has excellent wifi, a good air-conditioning unit in the sitting room, ceiling fan in the bedroom (perfectly fine even in july) and is very secure, with a large iron front door. There are plenty of shops and restaurants in the vicinity. Pantheon and Piazza Navona only a 5 minute walk from the house, and most of the major sites are reachable on foot (spanish steps, trevi fountain, etc). Only downside would be if you are an early or light sleeper, as lack of bedroom air conditioner meant sleeping with open windows - while the cobblestone street is relatively calm, it is still Rome, and there is a restaurant below, so it can be loud, although this did not bother us in the least.
