This is a wonderful apartment which is very well located. It's about a 30 minute walk from the Colosseum and an easy 10 minutes walk from the metro station at Piramide/train station Ostiense. It's also very well located for Ciampino airport -a taxi is only €30. The apartment has everything - most importantly air conditioning. The only issue we had was the street noise. It woke one of us - a very light sleeper - on Friday and Saturday night but did not wake the other.. So for any light sleepers, make sure to bring ear plugs!
