Myself and my family stayed in the apartment for three nights a couple of weeks back. We had an early flight and were pleasantly surprised we were able to leave our bags and check in by 12.30....Pablo was there to welcome us, he was extremely friendly and gave us a map and some personal favourites for food and drink.
The apartment itself was immaculate, it was clean, it was modern, and it was big enough for four adults without a doubt.
The other upside is of course it's location. It was a five minute walk to the colosseum and a further ten minutes from there into the hub of the city for a broader range of restaurants. It was a lovely walk home in the evening past the beautiful colosseum all lit up.
I would definitely be looking at staying in the same place if I'm lucky enough to return to Rome :)
