I stayed in Kai's flat for 5 weeks whilst on a placement at the hospital in Lewisham. The flat was ideal for commuting to and from work as it is close to good bus routes for the hospital or a 40 minute approx walk. The flat is also ideal location for getting into central London as it is a short walk to three different overground stations that take a very short journey to connect you to the underground.
The room was very big, with enough storage for a long stay. The kitchen is quite small, which makes it difficult to do anything in there whilst someone else is cooking but apart from that it was fine. There is lots of fridge and cupboard storage for each room and loads of pots, pans, cutlery etc to use.
Kai was a great host, and sent a very detailed information pack before the check-in and was always in contact by email to check everything was fine and to fix any issues that had arisen. Would definitely recommend for anyone wanting a longer term stay for work, or short term if you're looking to stay slightly outside central but with easy transport links in.
