The room we ended up in was clean and conveniently located to Roma Termini. However, be aware of a few things before you choose whether to book.
This listing represents multiple properties the owner manages. We were taken to one further from the terminal than expected. The host did move us to another unit, still different from the listing, but it was an uncomfortable check-in process.
The kitchen was nice, but there was nothing to use in it. They also provided no hand towels, only two bath towels.
The AC stopped working the second night. He did eventually get us a fan and was very apologetic, but it took some time to be resolved. The WI-FI also was spotty at best.
One small note, our listing mentioned a free meal and bottle of wine, however we were initially offered only 30% off. He offered a free meal when the AC stopped working.
