Rosalba is a fantastic host, really friendly and super fast at replying to any questions (even the annoying touristy ones). We arrived at 23:00 but despite this, she still spent a good 30 mins with us outlining the best places to visit and the must see attractions (really useful for three guys who'd done no research into Palermo before coming).
Tha flat itself was perfectly located - a short walk to the old quarter - and close to bus stops. Train station however is 30/40 minute walk though there is a bus there. Loads of restaurants nearby as well.
The flat was big enough for the three of us, has a nice little kitchen and a good sized bathroom. Rosalba kindly provided water for us (lasted half the week!) and plenty of towels, shampoo/soap etc.
Ultimately an extremely pleasant stay in Palermo with an excellent host always keen to help. Well deserved 5 stars and would highly recommend.
