Had a great stay at this appartment! The host was friendly and helpful and the appartment had just what we needed.
The location was about 10 minutes walk from the central train station in Ostia and from there we could buy train tickets to Rome for 1.50 euro.
There was a few ants in the appartment, but the host supplied us with a can of anti-bug-spray so it was really not that big of a problem.
