Alejandro's apartment is located in a strategic and central position, really close to Brick Lane and 10 minutes away from London Liverpool Street station, which is great if you get to London from Stansted airport. The room is not big but comfy, it's ideal for solo travelers and young couples. The Wi-Fi worked really fine. The neighbourhood offers pretty much everything: restaurants, clubs, bars, market, etc... again the tube is 10/15 away so you can easily reach The City or any other area of London.
I didn't manage to meet Alejandro in person, but he was always very responsive to my messages. I did meet briefly his (SENSITIVE CONTENTS HIDDEN), both very polite and friendly persons. In general, the communication between us was great. Recommended.
