As I am currently living (alone) in building 10.

I would like to live in building 28, because I think it would really help me with my studies.

And from what I heard there is a vacant room in (new ? What is new the builiding the room, freshly vacant ?) building 28 room 205.

{from what i heard the room 205 of the building 28 is vacant.}

I have done all of my training and now I want to get in the next training course which will start on June 15th. (What is the subject sports studies ?)

I will stay in here, without leave also I am scheduled for an interview on June 7th. Thanks to you, I was satisfied with living in the dormitory during my training, (so now I have successfully finished all of my trainings. What do you mean no point) I appreciate it.
