A fantastic base for our stay in Naples. It was so easy to get to the train station for Pompeii, Herculaneum and Rome - turn right out of the apartment and just keep walking straight. It takes around 10 minutes.
As others have noted, there is a lot of traffic noise, so if you are a light sleeper, bring earplugs (for a central location you will always get traffic noise!). The traffic in Naples is horrendous so it's best to walk everywhere and this location allows you to do that. The archeological museum, which is a must, is about 25 minutes. The apartment is very plainly decorated but it has everything you need and is immaculately clean. (Brits - they do have a kettle!). The mattresses are pretty firm, but I'm sure it's good for you!
The owner was very helpful and responsive. I would definitely stay here again if I were ever back in Naples.
