We really enjoyed our stay in Ostia at OstiaEnjoy. We were looking to travel at a reasonable cost and OstiaEnjoy was great for our family of six. The apartment was clean and spacious. Luigi and Sonia went out of their way to provide us help and information both before our trip and once we arrived. There are places to eat close by but we mostly cooked our own meals in the apartment kitchen. The coast is about a 5 minute walk away and there is a long pier out into the Mediterranean Sea. Access to Rome is easy, but takes about 1/2 hour to get to the Colosseum from the Ostia (Lido) train station. A quick transfer from the train to the subway is needed at Magliana but there is no additional cost for the transfer.. It is about a 10 minute pleasant walk to the Ostia train station from the apartment.
There is a 24 hour grocery store right by the train station where we would pick up food for the next day. We did not feel unsafe walking home through Ostia each night with our family.
The apartment is a perfect location if you plan to stop at one of Rome's most spectacular sites - Ostia Antica, the old Roman port.
To get to the apartment from the airport, we took the Cotral regional bus from the airport into Ostia central station for a few Euros. The schedule is online, but it can be a bit tricky to figure out the times and routes.
Overall, we had a great stay in Ostia at OstiaEnjoy!
