I really enjoyed my short brief stay at Daniele's place. He is so sweet and the timing worked out so he was able to pick me up and drop me off at the train station when I arrived and when I left 3 days later. The room is cozy and clean, and his roommates were very helpful. One helped me figure out the bus and train schedule and the other helped me print out my boarding passes for my flight.
The location is to the SE of London and it's about a 15-20 min bus ride to the Woolwich Arsenal train station and another 35 mins or so into downtown London. Very easy to navigate there. Just make sure that when you stay out late to mind the timing of the last trains because I missed mine one night but was able to take a train close to Woolwich and then had to cab the rest of the way back.
I was lucky enough to have Daniele make coffee for me on my last day and we had a chance to chat for a bit. He's a warm friendly guy and it was great staying at his place. I highly recommend it!
