Great place to stay for several days or for a long time.
100% renovated, sparkling clean, has twice as much amenities as one could expect (air-conditioning mounts in both rooms, iron, washing machine, dishwasher, fully-equipped kitchen).
The host is friendly, very thoughtful and will help you with anything that comes up (like she printed COVID-related documents for our return travel).
The apartment's location is ok - close to Termini station (it takes just 40-50 minutes and 2.5 euros to get here from Ciampino airport) and has good transport connection to the historical part of the city (10 minutes walk to Coliseum, 10 minutes subway ride to Vatican city).
You shouldn't wonder the area in search of Italian restaurants though - many of them are asian. Better go to Trastevere area - that's where true Italian cuisine is located (it is a place where Italians go, not tourists - so it is even cheaper than in historical center).
For our next visit to Rome (and there will be one - Rome is packed with sightseeing spots and you won't cover them all even in a week) we will definitely consider this place for stay.
