Valentina's Sweet Home Colosseo is an amazing value in a great location.
Even before my trip to Rome began Valentina was very responsive and addressed and questions I had withing a couple of hours sometimes even a couple of minutes. Having stayed in various Airbnbs before I am used to waiting a longer time for responses, or not getting any at all. Valentina also made reached out to us and arranged a transfer from the airport to the apartment at a very reasonable rate. When we arrived she was there to tell us about the apartment and point out all of the amenities. I can't say enough about how helpful she is.
Now onto the apartment itself. The place is about a 2-3 minute walk from the Colosseum, which is amazing. There are two very spacious bedrooms and two full sized bathrooms with a large common area. The couch is incredibly comfortable and she has all the things you might need to make dinner, wash your clothes, etc... and have a comfortable stay without having to go out and buy "one time use" items.
In the few blocks surrounding the apartments there are tons of restaurants, bars, stores and fast food places. There is also a taxi stand at the end of the block where the Colosseum is, which makes getting around Rome a breeze.
All in all I'd say that this place is likely to have anything and everything you're looking for.
