    "My first floor windows needed cleaning for a long time. Chris arrived on time and informed me several times a day about his situation - he is very communicative. She's very attentive to my comfort. She remembers everything important. She puts on shoe covers, protects the carpet, and vacuums after herself. The best window cleaner in London!!"
