We had a very nice stay in Marsalforn. The flat is very well situated, really well equipped (it has really everything you might need, like a coffee maker or a toaster...), and has a nice small balcony with a great view. It bit cold during winter but the heating works well and isn’t expensive: we spent about 1€ in 4 days. Victor is a great host, very helpful and with very good communication ; check-in and check-out are easy and let you be independent which is good. Go for it!
