We stayed here for 5 nights in June and would definitely stay here again.
The guest house is in a great location, just go to the end of the street and you can see the colesseum not even 100m away! So cracking value for money with the location. We walked everywhere from here, even to the appian way.
The owners are absolutely lovely and always willing to help you out, when we first arrived Vincent gave us a map with all the popular locations on and pointed out what buses to get from the hotel to various places.
The rooms are a tad on the small side (you're never in them anyway!) , but all en-suite with a telly, fridge and computer with free net access and they're cleaned everyday.
We really enjoyed our stay here and will defintely stay here again on our next visit to Rome.

Totally agree with the other reviews about this establishment. The locality is superb and the quality and value of the nearby eateries has to be experienced. Advice willingly provided by Vincent was excellent and invaluable.
The only word of warning is you cannot settle your account with anything other than cash. We tend to rely heavily on credit cards favouring this to carrying cash around especially when abroad but fortunately we were able to us the cash machines which were closeby.

The number one selling point of this hotel is the location. As promised, it is literally a 2 minute walk from the Colosseum, making it very close to all sightseeing buses and other attractions.

Vincent, Barbara, and the young girl at the front desk were always helpful and providing suggestions for food and sightseeing. They were an absolute delight!!
The rooms were tiny, but neat and clean enough. My biggest complaint was the darkness. The lights were fairly dim and there were workers outside so we had to draw the curtains on the one window in the room. It was nice to have internet access, but no English channels on the tv was a drawback.

We were given coupons for breakfast at two cafes nearby. The choice was limited to a pastry and cappucino or tea. This got a little tiring after a few days! There was always orange juice, coffee, tea, and prepackaged croissants available in the hallway by the front desk which was nice.

Overall, a good experience and would stay here on other trips to Rome.

This hotel is a great value for the price due to its location that is close to many of the desired visitor destinations in Rome, like the Colosseum and the Forum. Also good for the ease in which you can learn to navigate the transportation to other places you want to view. Our hosts were wonderful, taking time to make sure we were comfortable and had cold juice etc when we arrived, they had maps, gave us instructions on the buses or transportation to catch and how to get to places. They also had fantastic suggestions for local neighborhood places to eat that were definitely delicious and easy to walk to from the hotel, which was nice after a long day of sightseeing. The internet access and snacks that were readily available for us were a great bonus. While the rooms are small, they are comfortable and clean and there is plenty of hot water in our own bathroom! We did not go to Rome to spend time in our rooms, so size seemed irrelevant. Cannot say enough about the kindness of the owners of the Arena Hotel and would definitely stay there again if we went back to Rome. Plus right up the street was a super gelatto place that was open late in the evening...it quickly became a favorite stop each day!!!
