Moving in with boyfriend - want to do something special?

I'm moving in with my boyfriend in 9 days. After 2 years of unemployment (the same length as our relationship) he has secured a brilliant job just in time for us moving in.

I want to do something special on moving in day to say well done to him as it really has been a rough ride to get to this point and he has truly worked his butt off to get a job.

It's only a student couples flat so there's nothing too romantic as I'm still in university (he finished education after college). I just want ideas of what I can do for him that will be special as this day will only happen once. He is also moving out of his parents home for the first time so it makes it quite exciting for him whereas I moved out at age 18 so I've already been there and done that.

I'm 20 and he's 22 just for the record.
