Great flat for our short stay in London - 2 adults, 2 teenagers, plenty of space. Spare bed in foldout couch was perfect so kids could have their own space. Walking distance to Westminster area, then Uber boat to Tower.
There is a 3rd toilet room just off kitchen, I must have missed that in the listing because it was a pleasant surprise. Old building, but many updates. Would recommend. Immediate response with our check-in question - which was due to jet-lag brain, not lack of information provided ;)
