We had a great time staying at Antonio's flat. On arrival we were met by his friend Tiziana who was really kind to wait up for us (we were a little late), and spent lots of time telling us about the area and answering all our questions. It was a really friendly and helpful welcome.
The flat is lovely. It's in an old multi-storey building (18th century?) and the flat's on the top floor. So lots of exercise walking up the stairs! But it's fantastic having a roof terrace so well worth it. There is one bedroom and the lounge has a sofa bed if an extra bed is needed. It's a perfect location, right in the heart of the historical centre of Palermo, close to many attractions, restaurants, bars, etc. We took the bus from the airport to Politeama , and it's a fairly short walk from there.
Via Maqueda is a buzzing street and people party all night, especially at the weekend, so do expect some noise. But the bedroom is quieter as it doesn't face the street, and we had no trouble sleeping. In fact we slept really well - we found the bed very comfortable. There is air conditioning which can cool in summer but can also heat the room if you are staying in colder months.
One of the best features of the flat is the terraces. There is a small (standing room) balcony at the bedroom window, a larger one next to the kitchen - perfect for eating a meal at the table and chairs provided there - and a large roof terrace with several chairs and plenty of room. This offers fantastic views over the city and out to the surrounding mountains, really stunning.
In terms of facilities, we had everything we needed. The kitchen has a nice gas cooker and all the pots and pans you could need, plus a stove kettle, espresso pot etc. The bathroom is really nice with slate tiles and a modern shower, and there was always hot water when we wanted it. The lounge/diner is large and comfortable with a big L-shaped fabric-covered sofa and a smaller leather-type sofa. There's also a large glass-topped dining table and dining chairs. WiFi is provided and works well, there's a TV too but we didn't really use it.
All in all we thoroughly enjoyed our stay and found Antonio really good in terms of communication, flexibility with check in and check out, and general helpfulness. Recommended!
