I just finished a 5-week stay and I'm so sad it's over. We had an absolutely wonderful time at Alexander's flat. The flat was perfect for what we (two friends traveling together while also working remote full-time) needed - we had plenty of space to co-exist during the day while working. The living room/common space is very comfortable and cozy, perfect for hanging out. Great kitchen, great bathrooms - the washer/dryer was a huge perk too.
Cannot say enough about the location. Shoreditch was SO much fun and you're within minutes (if not seconds) from great pubs, great food, great nightlife. Old Street tube station is basically across the street but there's a ton to do in the area itself.
Alexander was a wonderful host - incredibly helpful and responsive. He cares a great deal about making sure his guests have a smooth experience.
Highly highly recommend staying there - I hope to be back soon!
