Obviously depends what time of year you go as to how busy.
Went over christmas and it was eerily quiet in the touristy bits. Obviously it’s low season but every bar person I spoke to said they’d never seen it so quiet.
Valetta is nice and busy. Reasonable shopping.
Sliema and St Julian are the best places IMO. Plenty of life and beautiful Maltese women, opposite of Bugibba which is full of British pensioners.
Thinking of spending Feb over there. Fly a bike over for £150 and stay in some nice digs I found for £12 a night.
Overcrowded roads. Cheap seafood. Very friendly people unless they’re in a queue then oowee you’d better watch out. About 18 degrees when I went.
