The apartment was as described and Claudio was very helpful and prompt. For 6 people, the apartment would be fine. More than that and it would be crowded.
It is only 30 seconds from the metro Vittorio Emanuele and Giardini Nicola Calipari. The neighborhood seemed safe, relatively clean, and quiet. There is no reserved parking if you drive, but we found a spot near the park and only €4 for the day.
The beds were extremely comfortable, the apartment was nice and warm on a cold winter night, and the showers had great water pressure and were nice and warm. The kitchen area was a perfect place to drink wine and play cards.
The €45 cleaning fee seemed a little much for a one night stay, but it was clearly stated in the house rules, so no real complaint. Just be aware that cleaning the dishes and taking out the trash are your responsibility and not part of the cleaning fee.
