Guido is an amazing host. He is kind and helpful and very good in English and can help you with restaurants, sightings, beaches and where to go in general.
Our room was very comfortable with a large bed, wi-fi, air conditioning and everything. There's breakfast included and the croissants were amazing.
We had a great time at Guidos BnB where the garden is perfect for tanning in the sun and cooling of in the big swimming pool (and playing with his little dog). It is also in walking distance from the beach and if you want to go to Capo Gallo you can even borrow bikes from Guido if you don't have a car.
We where really happy with our stay and we can recommend this place to everyone who want's to relax and have a good time in Mondello.
Bonus information: There's a Michelin restaurant only 500 m from the BnB. Bye bye Blues. Unfortunately we didn't go, so can't say anything about the food.
