Excellent apartment, in very good condition, comfortable, spacious and clean. A bit far from central London, but in a nice neighborhood, with lots of shops and restaurants around. Very close to Liverpool station, with good access to underground and buses that leave direct in places like Picadilly circus or Baker street (in case they go with babies and children is a better option than the subway). We had easy contact with Kiran on Airbnb. One problem with being with small children is that it is on a second floor (third in practice) and there are only stairs. The washing machine did not work, but Kiran offered to take the laundry to the laundry at their cost. Overall very good experience, I recommend it fully.
PS Follow the Kiran's instructions.
