Apartment is just outside the exit for vittoro emmanuele. Made travelling sooo much easier. Is a nice walking distance from the colosseum so a good way to go would be to take the train early
In the morning to the Vatican to queue and then walk towards the Parthenon then the colosseum and end up home. Many small stores and eating places nearby.
The apartment itself was spacious and great, can easily fit 5-6 people comfortably. Wifi worked well too.
