Very convenient location in Denmark Hill. Stayed for almost 3 weeks by Jadwin, and was easy to walk to KCH, groceries, gym and bus stations. Jadwin stayed in the same apartment, and was very friendly and approachable. It was a fairly comfortable stay.
The issues I had were that the mattress needs changing - i flipped it after a few days, because it gave me back pain, but that didn't do too much. I also had one shelf to use in the fridge, maybe 2 would have been better, considering I stayed for 3 weeks.
Otherwise, the stay was great, and I would recommend staying there for short trips.
