Carla's apartment was clean, well equipped and comfortable. The location was very good, in a safe and pleasant part of Naples with very good shopping facilities within a few minutes walk. It's also well located for visiting central Naples, being very near both metro and funiculars. The best view of the Bay of Naples is also a short walk away at the Castel St Elmo.
We arrived very late in the evening due to a delayed train, and the owners were very accommodating which was great.
The only problem was that a neighbouring apartment was having building work done at the time, which was rather noisy and started as early as 7.30am on some days. Presumably this won't be a problem for too long though!
