We totally misjudged this location, thinking it would be good to stay a bit outside the centre of London, but with two kids it was far too much walking. Yes, it was cheaper, but way more hassle and consuming travel wise than worth it.
The rooms are really tiny and can not be classed as family size. The sofa bed was 1,5 size, and with our 11 and 13 year old sharing, it was a squeeze. Luckily they get on very well.... Comfortable beds and clean and stylish rooms though.
No floor space at all for luggage! The staff offered us two joined rooms when we asked for a proper family sized room, but they would charge us for the extra room if we swapped, so we decided against this.
The room had 3 sets of bedding, towels etc, which must mean the hotel also sees this as a 3 person room, not a family one. But after asking 4 times we were given extra sets...
The staff were generally pleasant and breakfast was fine, but we would not stay here again unless we were only going to the O2 and Greenwich and had no kids or luggage.
