Althoug we haven't seen much of each other, our stay at Chris flat was very nice. The flat is in a quiet and lovely area with sweet cafes just round the corner and close to Primrose Hill. Chris and Renata were nice, helpful and welcoming. The flat was well prepared for guests including information sheets about the local area as well as info about London.
Although Chris was using his room sometimes in the flat we never felt uncomfortable.
We can totally recommend staying at Chris' flat.
