I stayed at this house for 5 weeks and really enjoyed it. Tanesha was a great host and communicating with her was easy. My room (No. 2) was very cozy and the desk was handy. The WIFI was stable and fast. The kitchen was well-equipped, everything was working and the fridge was brand new. The washing machine and dryer worked great.
The bathroom was clean and I really liked that it had a window for ventilation after showering (-> no mold). The main (electric) shower was broken, so there was a temporary replacement shower installed by Tanesha, which was working more or less OK.
The house was located in a quiet street, close to Brixton tube station (7 minute walk) and very close to several bus stops/lines (2 minute walk), so getting into the city was fast and convenient. There's a Sainsbury's directly at the tube station open until midnight every day (turn right at exit) so groceries shopping when getting home from the city was extremely convenient. There's also another Sainsbury's a 5 min walk away from the house.
The only thing I didn't like about the house was that it creaked a lot when someone was walking around (most houses in London are sadly built this way, though), so light sleepers may need to use earplugs at night.
I can recommend staying at Tanesha's house and will definitely consider staying there again at my next trip to London.
