Had a very pleasant stay at Lena's. I would highly recommend this to anyone. Excellent 24H public transport connections right outside the door. Gets you in the city centre in around 20 minutes.
Outside the room was the possibility of making tea, coffee and storing food in a small fridge as well. Only thing to keep in mind, anyone over 1.85m *might* think the beds may be a little short.
Overall we had a great time at Lena's place and would definitely visit again when in London!
