I would definitely recommend this place!
My brother and his family (wife and two small kids) had their best Italian holiday at Carmelo's apartment!
It is located in the old part of the city - very close to all the key sightseeing points. It is also very clean and neat.
Carmelo is the best host one can have, offering his help during the whole stay (picking up from the airport, bringing you to Erice etc.).
Also a big thank you to Carmelo's mum, a very welcoming and pleasant woman!
Grazie mille, Carmelo! and all the best for you from Adrian, Marta and two little boys :)
