You can basically get to any sights within 30 minutes. We went to a concert in the O2 arena and we got there in 15 minutes. The neighbourhood looked a bit scary at first but even as 2 girls walking alone at night we didn’t have any issues during our 3 nights stay. The entire place was clean and we had everything that we needed and didn’t bring with us. The walls are really thin but if you have any issues with noisy people in the other room the host helps you out.
