This is a really good apartment.
Starting with getting there:
We got the express train (every 15 min) from the airport to termini, and then got a taxi for €8. From getting on the train to walking in the apartment was less than an hour.
The apartment is Comfortable and homely, and really good value. Wifi is strong, kitchen well stocked and bathroom with a good shower and bath.
As with the photos, the Windows really do overlook the pantheon, and you get all the hustle and bustle (and singing) through them. You are staying in the heart of Rome and your friends (like mine!) will be very jealous.
There is a co-op supermarket in the opposite corner of the square and a ice cream shop under the apartment.
Everything is within 30 mins walk - Vatican, colosseum, Trevi fountain (10 mins) and piazza novanna (also 10 mins).
Lucia is a great host, meeting us on arrival and giving my daughter tips on where to get the best ice cream.
Will definitely be back and can't recommend highly enough.
