Pros:
Great location. The flat is in a quiet neighborhood that felt safe. Only a short walk to a grocery store and the Stockwell tube station.
Henry and Molly were easy to reach and quick to respond. On our last day, they let us leave our luggage upstairs with them for a few hours after our checkout time, which I really appreciate.
Comfortable bed.
Washer and dryer available.
Nice view of the garden from the kitchen.
Cons:
We were told the thermostat would be set to 23° at night, but some nights the heat didn't seem to be on at all. We were chilly for most of our stay, unfortunately.
The shower head needs replacing. The water pressure is low and some of the water sprays out at a weird angle.
This is a basement flat, so the dampness and spiders weren't surprising, but still a bit unpleasant.
We were not provided with any extra towels or bedding.
The flat is down a few steps and the bathroom is multi-leveled, so this is not a great place to stay if you have mobility issues (luckily not a problem for us).
The garden is only available for use when the hosts and their daughters are not at home.
Overall it was fine, just not as comfortable as expected.
