Cian's place was nice and spacious. He was very communicative and gave a great list of recommendations for London.
Each bedroom is on a different floor so you get some extra privacy there. The kitchen is in the basement level with one bathroom. First bedroom is on the ground level with the sitting room. Second bedroom is on the first level with the second bathroom. Third bedroom, kids room, is on the second level.
The kids room is suitable for two people, one in a twin bed and one in a "sofa bed", but be aware the sofa bed is an Ikea pull out that becomes basically a floor mattress.
The bed in the first bedroom was a bit uncomfortable, but fine. The bed in the second bedroom was very comfortable.
Both bathrooms were good size.
The wifi worked great. There is a washer and separate dryer. Kitchen has all the utensils needed to cook for yourself. Big TV in the sitting room.
Within a few minute walk of Elephant and Castle underground station. It was very easy to get around from here.
Would definitely stay here again.
