We had a nice stay at Giovanni, Laura & Martine’s. The space looks just like the photos, and is very centrally located - just steps from the train station, which is great if you're planning on visiting other areas such as Sorrento, Pompeii, etc. The bus from the airport to the stop near the apartment is only about 20 minutes as well, which is ideal.
The terrace is beautiful to watch the sunset with a glass of wine! We enjoyed some stunning views up there.
The only thing of note to other visitors - the area is quite busy and can therefore be noisy during any time of the day or night. Since the weather is getting warmer, we had to keep the windows open to sleep, but this did result in some restless nights. We're quite used to living/sleeping in busy metropolitan areas, but it could sometimes be loud, even for us. Just something to consider if you are a light sleeper.
Giovanni, Laura and Martine were so kind (we had the chance to meet all three over the course of our stay!) and are very happy to help you with suggestions, recommendations, and information - so don't hesitate to ask!
