I'm very happy with my stay at Rashpal's house. It's 2 min walk from a bus stop (bus operates 24/7 and drives by every 10-20 min). It might seem far from downtown (20 min on bus plus 30–40 min on tube) but public transport is very comfortable and room is super cheap so it's ok. You might be a little confused by how to turn on/off the microwave or the water but Rashpal's and his mum were always there for me, ready to help and explain things. Thanks you, Rashpal! All the best!
