In one word - Outstanding!!! Ben was amazing, even before we arrived. Having never rented a flat before, we had a ridiculous amount of questions and Ben answered all of them super fast - never more than 24 hours and put our minds at ease before we ever left home. The flat is as beautiful as it looks in the pictures, very spacious and bright, the bed was very comfortable, the water pressure in the bathroom was perfectly fine - bathroom was very large BTW - having all that space for our visit was simply perfect. We stayed during the Olympics and Ben put in Cable for our stay so we could watch all the coverage when we were not at events - above and beyond what we expected. We had the rooftop "deck" area available also - and had very good weather, but only took advantage of it once as we were simply either too busy or engrossed in the Olympics!
The flat was very easy to keep clean (we can't stand messiness) - we had asked abut cleaning services, but found we really didn't need them after all. The kitchen was fantastic - everything you could want to make anything you can think of - it was a great pleasure to be able to make some of our meals - although there are so many great places to dine around the area.
All in all - the place was simply perfect for us - location is ideal, 5 minute walk to tube station (3 lines) or bus stops to get anywhere in the city; the space was wonderful for a longer stay, the decor was very attractive and bright and calming - great after a hectic day at Olympic events! and Ben - what can we say about Ben - he was an absolute delight to work with - if you knew some of the questions we asked and his unfailingly cheerful responses, you would know what I mean.
We will most definitely be back - sooner than we thought, simply due to how great our stay was made by this most comfortable flat.
We would recommend Ben and his excellent flat without any reservations.
