We wanted to visit the Ostia Antica archaeological site, and others in the area, and this was an ideal base for our stay. There was only two of us, but this apartment was cheaper than hotels in the area. We didn't use the other bedroom, so there would be plenty of room for 3 people, and I believe the sofa could be made into a bed too. Outside, street parking was no problem in late September. Dario was a great host, when we found there was no hot water he came round within 15 minutes and sorted out the boiler. A great apartment.
Lido di Ostia itself was a bit dead at the end of September, so there wasn't a huge choice of restaurants nearby. We found the Falco d'Oro in Via della Tolda, just behind the apartment block, was very good. A bit basic looking, but good food, and you needed to get in early before it got full. Also the bakery on the ground floor of the block did good take-away pizza.
