Diego had excellent communication before, during, and after our stay. Entering and exiting the flat all ran very smooth. The location is close to Clapham Junction and several bus stops, which makes getting around easy. There is good closet space for clothes and personal belongings. Our main issue was cleanliness. The bathroom was not up to par and there was a good deal of dust (but I understand that with no AC, windows have to be kept open a lot so it's quicker to get dusty). Friday and Saturday nights your bedroom will be directly facing several bars, so I'd recommend some good earplugs to sleep through the noise.
Some stairs to get to the flat and inside the flat, so not best for elderly or handicap guests. Nevertheless, compared to other hotels and rentals in London, Diego was less expensive and that allowed us to pay for other travel costs. :)
