I stayed at Olah's flat with 2 friends as we were going to a music festival in Upminster. Was perfect for what we needed as it was a place for us to base ourselves whilst we were out most of the weekend! It was a funky, art-deco, warehouse - style flat (with a music room!), based in an industrial park - close to public transport links, and night buses from central London also operate in this area (but take a very long time as it is the end of the route). Olah was a great host, reponding to all communications very quickly. She was in Berlin at the time and had her friends check us in, who were also fab! Was definitely value for money - would recommend it to anyone that is going for a couple of days around that sort of area, as some of the train stations to get back from central london are closed from about 11pm-12am (you need to change about 3 times, which during the day is no hassle), and taxis are very pricey! Thanks for having us, Olah - we had such a good time! :)
