This is a very nice place overall. A group of us (3) were in town for a month working at the StazioneZoologica. Overall, It was comfortable and nice to base out of during our time in Naples. The Mergellina area is quite vibrant with its proximity to the water and can be a bit busy with traffic funneling in from the nearby tunnel so it can be a bit loud at times during night (be prepared for some honking traffic). You get a sense of the real working and playing city given its away from the heavily tourist part. The local produce, gelato, pizza (50Kalo!) and chalet shops were great and proximity to the train station was a plus. We loved the terraces (there are two) and took advantage of the lower terrace more than the upper terrace, just out of convenience. We cooked a bit (there are two hot plates which work well) and we packed lunches to take to the Stazione. One thing that would have helped us (and likely will help future guests) are some more kitchen amenities like more knives (especially bread knives for slicing bread/etc), as well as containers (Tupperware?) for storing food/taking lunches from leftovers (pasta, etc.)--this won't affect those who don't do much cooking. Guiseppe was very responsive and a great host. He was always available to answer questions and help. It was nice that each bedroom had its own small bathroom--convenient. The surrounding neighbors were quiet.
