Carlo and his wife are perfect hosts.
Apartment is lovely, very clean, fully equipped and centrally located in Sliema, within 10 min to ferries (easy access to Valletta and trips to Blue Lagoon/Gozo) and St. Jullians/Peaceville. Neighbourhood feels very safe and there is a small grocery shop and pharmacy 1min walking distance from the place (big supermarkets are located within 10 min. walking distance).
Our hosts were very flexible and helpful. We felt very welcome and we received many useful tips from them.
I definitely recommend this place and I hope to have opportunity to come back there in the future!
