We booked this when it was a brand new listing and it was even better than we hoped it might be.
It's super close to the Colosseum, yet tucked away and private. VERY secure. Fantastic gelato shop across the street and an excellent restaurant around the block, La Taverna dei Quaranta--better and cheaper than the tourist restaurants immediately across from the Colosseum.
The apartment is BEAUTIFUL when you enter it and my favorite part--the air conditioning was superb. My only regret is that we didn't get to spend more time in Pietro's wonderful place. Well done!
