We were really happy about this apartment and I would recommend it to every couple.
First of all Antonella is the most dedicated host I have ever experienced. She will give you a warm welcome toghether with her husband and child upon arrival, and no matter what you ask (questions about your arrival, the city, nice restaurants etc.), she will respond immediately. Even when you have no questions, she will send you a message via the chat just to make sure you have a pleasant stay. We really appreciated that!
Second, the apartment was clean and of great quality. Everything in the kitchen functions perfectly, the shower is amazing and the bed is of great quality. Furthermore, in contrast with many other airbnb offerings, this apartment was even bigger than shown on the pictures, which was a nice suprise.
The location is also fine. From the airport it's a ~30 minutes drive to the central station and from there you only have to walk 5-10 minutes. The old center is also within a 10 minute walk. The only critical feedback I can think of is that the harbor and palace are a litte bit far. This is, however, easily solved by taking the step which you can find on every corner of the streets.
All in all, I think this apartment is really worth the price. Especially considering the higher prices of so called "similar apartments" which are way smaller and of lower quality.
