Fantastic apartment and fantastic host. Looks just like the pictures, was incredibly clean and lots of free coffee! The kitchen was basic but perfect just to sort coffee, breakfast and picnic. Perhaps don't plan a big meal at home!
Good location for fun evenings in Trastevere, if you are ok with steps back. A bit of a longer walk to some of the sites (Colosseum was about 40 mins) but it's the best way to see Rome and meant it was quiet enough for a restful sleep.
Simo was great at communicating, gave us good advice before we arrived, but did not interrupt our stay.
The only thing we would change is to add an extra curtain to one of the windows, but that's very minor!
Highly recommend for a good value short sightseeing trip to Rome.
