We went last year with the children - really enjoyed it! Of course, English is no surprise to anyone in Malta, but the program “Children + Adults” was very convenient for us, so we could go with the whole family.
For adults, I will say from myself, the course is simple and completely annoying - so, by and large, communication in a foreign language. It is more interesting for children: there are all thematic games, and films-songs in English, they learn a few words - but this is not also within the framework of school studying, but as a summer camp. We were more interested not only in studying English, but in rest with the whole family with pleasure, and with a little benefit for the younger ones: English is useful at any age.
The school is well equipped, everything is new, the teachers are young, 25-40 years old. Very beautiful location: all city sights nearby, where there is a walk (Sliema as a whole is one of the busiest cities on the island). About the sun / beaches, etc. I will not tell you, everyone knows about Malta. We were lucky with the weather, there were no rainy days: only a couple of overcast days, but we managed to take some time off from the sun for them, so we were not upset.
Good sightseeing offers, there are a variety of options for the wallet and interests - we have even chosen a few, although usually we do not take "package" offers from our hotel on vacation (well, here from the school). Affordable cost as a separate bonus - even taking into account the trip with the whole family (4 people), we could afford it. In general, we recommend, we are satisfied.
