We have stayed at Matthew's apartment in the middle of March, and we wouldn't change anything even if we could.
Communication with the host was lucid and clear. He made sure we had a ride to the apartment from the airport for a fair prize. All the little stumbles we had during our stay were quickly resolved. Apartment was clean and well equipped. Air conditioning was pre-pay, but for 1€ we kept ourselves warm through the entire evening. We deeply appreciate this eco-friendly system in Malta.
