Myself and my partner stayed here for 4 nights and found it perfect for what we wanted. The apartment is a great space with everything you’d need including a great balcony for relaxing at the end of the day.
The apartment is a few minutes walk from the metro (very easy to use with a 72hr ticket costing €16). The Colosseum was about a 15 minute walk and you can either get metro or keep walking around the rest of the sites (we chose to walk and did about 8-10 miles a day).
We found Vincenzo to be a very helpful host. He met us on arrival, gave us tips and recommendations and always responded quickly!
If we visited again we would definitely stay here.
