We stayed at Luisa’s only for one night but we really liked the neighborhood - quiet but still with Napoli character. There are small grocery stores and a bakery nearby as well which was great for our kids. It is also just a 15 minute walk to the train station.
For those with little kids like us- neighborhood is great but it is possibly a little far from some of the more famous sites. For adults, a 10-15 minute walk is nothing but for little ones it may accumulate into a tiring day. It is not an apartment for long term if you like cooking on your own (no stove or bowls/plates) but it is close to tons of really nice restaurants within 5-20 minutes.
Luisa welcomed us with some really cute decorations which we appreciated and some baked goods and tea/coffee. Great place to people watch from the balcony as well. Heat will cost extra but works well in the winter.
