Dario & Bea's flat at the Colosseum exceeded our expectations. It has everything a family of four could need: comfy beds, a fully stocked kitchen (even with a wash machine!), and most importantly, a host (Dario) to great us who was very helpful in telling us everything we needed to know to navigate Rome. Several restaurants are right around the corner, plus a fantastic bakery where we bought bread every morning, and yes, the Colosseum really is just a 10-minute walk (we happened to arrive on the first Sunday of the month, when admission is free). And everything else in the city is just a short subway ride away (two stops to the Termini train station, eight to Vatican City)...and the station is just a few minutes walk from the flat. I'd highly recommend Dario & Bea's flat, and would stay here again.
