I'm living in Broadgate Park at the moment and can't wait to get out.
First and foremost, the internet is absolute rubbish. It's very temperamental and often goes and returns as it feels. The wifi connection where I am is virtually non-existent so I've had to use a cabled connection.
Secondly, there is often only 1 or no bars of phone signal in my block which makes calling or texting people very difficult and if the internet goes down I can't use my 3g. This is a problem for everybody I have spoken to in my block, not just my own phone.
I've also come across, from when I moved in, a large number of silverfish insects walking around in my room and in the en-suite part which is quite disgusting.
Those are the main faults of the actual Broadgate Park premises. The other things that made it worse are down to the people in in. My room happens to be placed directly above the front entrance of the block. This means that I can constantly hear everything everybody is saying. On numerous occasions I've had exams and people have been just outside my block shouting and screaming their empty drunk skulls off until past 4am. I can also always constant smell cigarette smoke and weed seeping through my windows.
Lastly the walls in my block are, indeed, very thin. The person directly above me always plays his music very loud (the same song over and over again at 1am is enough to drive anybody insane!). The reception tell you to call them and they'll come over and fix it. There is, however, no signal.
The biggest problem about Broadgate Park is that a huge majority of students have a complete and utter total disregard for everybody else living there. Even as I type this I can hear some heavy bass coming from a room near me.
If you are a person who likes their sleep and likes to work in peace and quiet come exams. I would recommend that you avoid this place.
