This apartment meets every expectation: it's very well furnished, everything has its place and its purpose, it's really CLEAN and well-maintained. Nothing's broken, nothing wobbles and nothing is stained (yes, this should be the default everywhere, but...)
The bedrooms are spacious and with ample storage space and the most comfortable mattress I have ever slept on, the bathroom is impeccable with a roomy shower booth, and the kitchen is small but has everything you'd want to cook, including not only kitchen gadgets but also baking paper, olive oil and spices, and best of all, a dishwasher.
Roberto was very accommodating and quick to reply to our messages.
The only thing I wish was different is the location: the apartment is right next to a car workshop and a car wash, which means there's loud banging, shouting and noisy machines from 8 a.m. even on the weekends, which is not great for either sleeping in or working from home.
The other thing to note about the location is that it's a bit far from the centre, and transport in Palermo is horrendous by bus or by car, and unfortunately, walking is bound to give you a heart attack if you're not used to cars disrespecting all rules, signs and traffic lights and almost running you over every time you cross the street. The only good way to get around is to take the train, which stops a few minutes from the apartment, but only operates in 30-minute intervals.
On the other hand, there are several excellent restaurants, supermarkets and gourmet food shops within 10 minutes by foot, so you don't need to go far away :)
