We just returned from a 2-day trip to Rome and stayed at Valeria's apartment. Valeria quickly replied to our booking request and explained that even though the apartment "Aureliano" was not available, she could offer us an identical flat in the same building, either "Diocleziano" or "Costantino".
I appreciated her prompt reply as we were booking this only 3-4 days before our arrival, and was pleased to see that she was helpful in offering us an alternative.

I have a lot of positive things to say about our experience with Valeria & her flat.

1) No late check-in fee (unlike many other flats on Airbnb, where the owners charge you sometimes ridiculously high amounts (up to 50 Euros!) for checking in after certain hours)

Our flight was arriving late (after 10 pm) and I informed Valeria regarding this, she was very flexible and met us at the flat at 11 pm on Friday eve for check-in. We really appreciated this (and not being charged extra!)

2) Location: This flat is within a 2 minute walking distance from the Colosseum. It is ideal to reach the Colosseo metro (4-5 min walk). There is a Carrefour market in the next (parallel) street that is open during the day so that you can buy some groceries and food if needed. The street Capo D'Africo is known by taxi drivers and it is a quiet street.

3) I think this flat is most perfect for 3 people. The double bed inside the main bedroom was very comfortable - it was hard just the right amount with great pillows (I have back problems and this bed was amazing for that). Also a big closet with lots of hangers was provided.

The sheets and the whole apartment in general was very clean. The sofa bed had already been made for our convenience before our arrival.

The sofa-bed in the living room was also very comfortable - our friend slept there and had no problems. It is for 2 people (but will probably be more comfortable for a single person as it looks like a 1.5 person bed)

Overall, we had a lovely stay. The bonus part of our trip was when Valeria's daughter dropped us to the airport for a discounted fee (this was 15 Euros cheaper than taking a taxi or even the Leonardo express from Termini!) upon our departure. We are very glad we used this option - it took us 30 mins to reach the airport- and would like to thank Valeria & her husband for offering it to us.
