Hi congratulations on being accepted. The state hospitals (which you attend in 3rd/4th year) in Cyprus are primarily Greek speaking. Current students have found the language barriers one of the biggest problems to their experience with respect to this. 80-90% of your time in the hospital will be spent listening to Greek so if you don't understand, that is a huge amount of time wasted.
If possible you should learn Greek in the first 2 years if you plan on staying in Cyprus, they may make this compulsory over the next year or two.
Accommodation is pretty straight forward to find, my advice would be to have a look at a place in person yourself when you get here, if that means staying in a hotel for a couple of nights so be it. I wouldn't recommend the student halls as I have only heard bad things; they are expensive for what you get and the quality isn't fantastic. A lot of student move out of their apartments towards the end of the academics year and post up on Facebook these would be worth having a look for. You can ask the school to recommend estate agents through there 'support service' but I would be extremely cautious of this as people have ended up with apartments with problems. (Marios the estate agent has a questionable rep)
