I was travelling alone and stayed for one week in Irene's place. I had a really lovely experience and everything was perfect for my needs.
This was a working holiday and so a very strong Wifi connection was very important to me and I had no problems at all in this appartment.
The location is excellent for exploring, it is in the heart of the old town with plenty of restaurants and sites to see all within a short walking distance.
The apartment was quiet and felt very safe. The kitchen was fully equiped and clean with two outdoor areas making the whole experience really wonderful.
For a fee (which was cheaper than the taxis), Irene picked me up from the airport which was a bonus for me.
I would definitely stay at this apartment again if I visit Palermo in future.
