This place is amazing. Location wise it couldn't get better.
We had to get a taxi from the train station because we had broken suitcases, and didn't fancy trying to get them on and off a bus. The taxi only cost 10euro.
It's walking distance to all major attractions. We walked to the Vatican, Trevi Fountain, Spanish Steps, Colosseum. We even went for a stroll into neighboring areas such as Testaccio.
You can get a Tram, but walking around meant plenty of pit stops for Gelato.
The area Trastvere itself apart from good location for the sites, is amazing for anyone food obsessed. The little lanes and alleys come to life, and the food is amazing. So many little restaurants and cafes, and a few really good spots for gelato.
The apartment itself was nice. Wifi worked a treat, and was comfortable to come back to at the end of the day.
There's isn't an elevator, but to be honest, the stairs are a blessing in disguise once you find a good gelateria.
