My girlfriend and I came to Sasha's flat for five days at the beginning of May and everything was great. Sasha was really welcoming and helpfull and not invasive at all. He was there to help us when we needed it.
The flat's location is exactly what you're looking for when you want as much hanging out with friends in the lively Hoxton neighborhood as taking the public transportation to go visiting the London great places. In a word, it is well located.
