We had a great stay in the appartment with 5 people so we almost had each our own bedroom with private bathroom, which was a luxury. One thing to be aware of is that the appartment has four floors, so a lot of stairs ;-)
KItchen is on the lowest floor, dining table on the first floor, sitting area on the second floor, master bedroom on the top floor. Other bedrooms each on one floor. No problem for us, but on first sight the common areas did not appear to be as spacious as we had expected.
Location is great, near Paddington station and a lively street with shops and restaurants. The appartment is off the road, really quiet.
