We had a great stay at Alex's flat!
The flat had everything we needed, kitchen is well equipped so we could prepare most of our meals at home.
We were also attending classes and working from the flat and we had no issues with the internet, which is really important.
Alex was a very responsive host, promptly answering our questions.
Last but not least: the location! Dalston is a very vibrant area, full of nice restaurants and bars and also with good transport connection to the city center.
