I stayed at Coleman's flat while in London to work at Wimbedon, which was a convenient 20-minute, one-bus ride away.
The building itself is so-so. But don't be discouraged by that; it felt more than safe.
I can't say enough about the immaculate condition of the flat, which was clean and bright, renovated and equipped with everything you could possibly need.
It has a veranda around two sides of it, which made it feel more open than a typical flat.
The Wifi was speedy, the bed was comfortable. The shower pressure was great – all the things you need on a work trip (or even a holiday).
It's a five-minute walk to Clapham Junction rail station, which can get you anywhere you want to go.
All the amenities you need are nearby, including big supermarkets, coffee shops and restaurants.
Coleman was super cooperative with the check-in process even with my flight delays, and checked in regularly to see if I needed anything.
I would stay there again any time.
