Overall this flat/apartment was excellent.
Very clean, modern, in a great location (for tube & parks). Rooms were of a good size, and the courtyard was great (and would have been used more had the weather been nicer!). There was a high chair available to hire too, which was great.
The bed mattress must have been changed since the last review, as it was amazing!
It is on a bit of a main road, but you can't really hear it from the flat. Great for taxis too.
Wifi was a bonus, but the extra power point next to the modem in the lounge room, which would have made an excellent iPad/iPhone charging station, was obstructed by the heater. Really minor issue, but annoyed me!
The only niggle I have with the flat is that the steps leading down from the street to the front door were steep and narrow, and difficult with 2 large heavy suitcases and a toddler. This is not mentioned anywhere in the description of the place, nor are there photos. Because of this I would say it is not ideal for toddlers and buggies/push-chairs, but older (5yo+) kids who can navigate stairs with ease and have road-sense would be fine.
The agent was very helpful and accommodating, and we had no trouble with booking or initial access to the property.
All in all a very enjoyable stay.
