Stayed at this hotel because it was so close to the airport, and close to the extraordinary ruins of Ostia Antica -- hundreds of buildings from the ancient port of Rome. You can get to the archaeological park by free public bus that stops outside the hotel or walk several kms. The hotel is a good value. The room was fine and the staff very friendly. It's a bit of a walk into town to find a restaurant or bar. The hotel itself has only a modest bar and no food in the evening, although the breakfast was very good.

We choosed this hotel because we arrived late night from Amsterdam and there wasn't train to Rome, so we decided to sleep near the airport to take the train to Rome next day, The hotel is simple but it was cleaned, nice bed and offered a breakfast included in the rate. This was enough for what we were expecting.

Ok so you're on a budget. This place is 10 mins from the airport. 15 euro each way in their bus. You need to book it. 3 euro per hour wireless in the lobby. 10 euro for pizza and large beer in Nonnas restaurant next door. Clean basic secure rooms and friendly staff. No complaints.

We booked 7 nights in the Ostia Antica Park Hotel as we were visiting family in nearby Acilia. The location is a couple of kms out of Ostia Antica on a busy road. If you are looking for places to walk to eat and drink this may not be the hotel for you, however as a lower cost alternative to Rome it was great. The room was perfectly ok. A comfy bed, nice terrace, TV, minibar and an extremely powerful shower. All spotlessly clean. Breakfast was a buffet affair with a variety of pastries, fruit, ham, cheese etc. There is a restaurant right next door which does great pizza and you can buy it as a takeaway to eat in your room if you wish (2 good size pizzas cost us €14). The communal bar and lounge areas were clean and comfy and the staff were very helpful.
It takes 30-40 mins on public transport to get into Rome. Take the 04 bus from outside the hotel to Acilia Station, and from there pick up the train to Basilica Sao Paulo (also known as Pyramid). From here you can access the whole metro system and if you buy a whole day ticket you get unlimited bus and train travel for 4€.
The hotel offers a shuttle bus to the airport for 15€ per room, but this stops running at 11am so for afternoon flights a taxi is needed (approx 35€).
We paid €351 for 7 nights through a booking site, and to be honest were delighted with the value for money and will certainly use the hotel again.
