Places to write a dissertation over the summer

Hey guys! I'm in my final year of my two year masters degree and will be working on my dissertation over the summer, my deadline is mid September. I struggle to study at home due to distractions and usually study at my university library but that gets pretty stuffy in the summer and I would like to switch it up and study somewhere new in my final few months as a student.

I am looking for somewhere with large windows I can look out from, air conditioning and a bit of a buzz as I hate dead silence. Obviously I will need a charging port and space to work, I'm not fussed about being able to eat/ buy food there. I live in East London but am willing to travel to central or South East london (and north or west if the place is extra special). I work 9-5 from Monday to Thursday so somewhere open evenings and weekends would be great.

Any suggestions would be much appreciated! Thanks!!!
