We were staying at this hotel just for one night. We had an early flight out, and their website said they were near the airport. This is true. The hotel shuttle (not free) in the morning was easy and took under half an hour. The room was fine and the shower was one of the best we had in Italy.
On the downside, the hotel's website made the walk from the train station to the hotel seem easy, only 800m in a straight line. We were lucky that someone from the train took pity on us and offered us a ride, which was at least 4 minutes and took several turns on busy roads with tiny sidewalks. I would not recommend walking it. The hotel offers a shuttle from the train station, but I believe you need to set it up in advance.
Also, the restaurant at the hotel, while delicious and decently priced, was severely understaffed. There was one waitress for the whole place, which, except for us, was filled with about 6 groups from 3-10 people each group. Needless to say, the poor waitress couldn't get to everyone, so the service was really slow.

Agree with most of the reviews mentioning problems with location; poor signage from train station and we ended up walking to the hotel for lack of info as to how far it was--survived traffic nearby just barely, lugging wheeled case through ditches full of rain for half an hour. Take the bus! Hotel is so far from 'village' and ruins that you need to. Front desk was exactly as helpful as they needed to be and not a bit more friendly than that, though they did change our room when asked and were prompt with the wakeup call.
As a little village, most things (very few to begin with in the way of shops or cafes) close in the afternoon; we had planned to visit the ruins but for no apparent reason and with no advance warning they were closed that day (not the fault of the hotel of course but be prepared--it's Italy--but if this happens you may consider whether there is anything else to do there for the day--not in winter. the hotel has 3 or 4 channels of TV, all Italian.) Breakfast basic, pizza at bar ok but does not match description given in elevator menu, be warned.
As to the quality of the hotel--clean enough but barely adequate, comparable to cheap plywood constructs I've stayed in in places like remote Turkey or Ukraine (for far less money). Hardest beds ever which is saying something in Italy--lost a lot of needed sleep the night before a long flight. Entire hotel 'decorated' minimally in the 1970s and not touched since, apparently.
The advertised internet costs 5 euros per half hour to use--be advised that the little "Bar" in the village, last one on the row going toward the ruins, has FREE internet for customers.
The shuttle service was fine but they did tell us we had to leave at 7.00 a.m. to allow an hour to get to the airport, which in fact took 20 minutes so could have left an hour later. We wished fervently that we'd stayed in a B&B in town instead, all in all.

The hotel was difficult to access without your own transport, the so called shuttle service was over priced and only available at certain times. On the day we left we tried to book the shuttle for 4.00pm but were told that at 11.00 it stopped and did not re-start until 5.00pm. The shuttle cost 10 euros per person one way. A taxi was quoted at 40 euros and the hotel is only 8 km from the airport! We used local buses for 2 euros total! The bus stops adjacent to the hotel and takes you to Lido central and then you pick up the airport bus SO EASY AND CHEAP!. The hotel was clean and ample for our stay breakfast was the same every day and very limited no fresh fruit which would have been nice. MY TIP use local transport everywhere and shop at the local GS store and use the restraurants and bars in the villiage

We expected a 3 star and paid 130E for our last night in Italy. The web sites we checked assured us the hotel was 3 star, had wireless internet throughout the 'entire' hotel (Booking.com) and was air conditioned.

The beds were the most uncomfortable and noisy (creaked loudly with every movement, looked like home built wooden boxes with a thin mattress on top) I have ever experienced in a hotel, the room was tiny and the TV even more minute. There was nowhere to put anything in the equally minute bathroom. The air conditioning had been turned off two weeks earlier, we were told, and internet was only available in an office adjacent to the front desk.

When we arrived in Rome by train we called and were assured that if we took the appropriate trains we would be picked up from the Ostia Antica train station - just call and let them know we had arrived. No mention was made that there are no pick ups between 11.00am and 5.00pm. We might have discovered from the web page, but we didn't, and we did have their assurances. We arrived around 3.00pm and called and they told us which bus to catch. That left two no longer young retirees with heavy bags (one recovering from knee surgery) to negotiate a horrendous footbridge with long flights of steps, narrow unmade edges to the road and an anxious period as we tried to find out which direction we should be going in. We lugged our cases onto the bus and when we got off we had to cross one of the most dangerous roads I have encountered.

We arrived at check in and there were two men and a woman behind the desk. After seeing the poor standard of our room I went downstairs to express my dissatisfaction. I was informed by the young man at the desk that he was unhappy too, it was a standard twin room and there was nothing to be done! He explained that no one could pick us up because he was alone at the desk - not my observation - that the air conditioning was not broken, it had been turned off, that there was no wireless internet in the hotel. His attitude was 'smart' and unhelpful.

We are pretty seasoned travelers. We were fuming about the pick up debacle, but more importantly don't understand how this hotel could ever have been given a three star rating. For a two star, it was OK.
