We had a very nice stay at Michael's apartment ! The place is very big, bright and the decoration is amazing ! It is ideally located in Sliema which is less busy and touristy than Valetta and where you can enjoy the real Maltese life. Lots of supermarkets and restaurants in the neighborhood. It is very easy to join Valetta though (with a short walk and a nice 5 min boat shuttle).
We did not see Michael but the communication went very smooth as he always replied quickly to our enquiries.
