It’s all good, just as others have said. A very easy walk from Termini station (though the jagged sidewalks will challenge your roller bags). It’s less than a 5-minute walk to a full-fledged supermarket, and about a 10-minute walk to a variety of restaurant options (Vale recommended a couple of them to me, and both were quite good)…also a take-out pizza/kebap shop within the block. Metro station is a 10-minute walk (but if you like walking, you can do just fine even without the Metro; e.g. the Coliseum is no more than a 20 minute walk, and the furthest afield attractions, like St. Peter’s square/Vatican are a 1 hour walk, with lots of interesting things to see in between). And the apt. is well-stocked with Rome travel books and several Rome maps.
The kitchen is fully equipped (stove, microwave, frig, etc.. all worked well), including several spices (basil, oregano, etc…) and coffee supplies, plus plenty of dishes, pots, pans.
The shower was the best I’ve experienced in Europe, with plenty of hot water (though as just 1 person, I probably wasn’t a severe test), and soap/shampoo are provided.
The bed was extremely comfortable, and (most important to me) the building was very quiet at night (and there’s no traffic noise at any time)
Vale is a most congenial host, and I’d think you’d have an excellent experience at her apt, just as I did.
