Definitely cozy, it is womb-like. There is a great shower with multicolour lights, turn on some music and have a dance party in the bathroom. Loved being able to wash clothes, and the kitchen is usable, with a small fridge. The place is smaller than the photos make it appear, perfect for 1 or 2 people.

In terms of public transportation the nearest train is the Cumana, about a 10 minute walk, or the funicular near Piazza Amedeo . I'm a fast walker and with luggage the walk was about 12 mins, but probably more likely 20-25 minutes for the average human.
Also don't check in after 7 pm, they charge a 20 euro fee.
