Great stay if you just need somewhere to sleep during your stay in London.
Pros: Reasonable price. Nothing too fancy but definitely clean apartment and room. Strong WiFi. Quiet apartment. Nice window view. Room has table, chair, and lampshade. Towel, fan, hangers, and extra blanket (in addition to the duvet) were provided. There are toilet paper and hand wash provided. Kitchen has fridge and microwave. Quick responses of Host (Kamal) and the Caretaker (Hussein). Friendly welcome. Tour of the apartment facilities provided. Accessible location for commute (10-15 minutes walk to/from public transpo). Secure building. Nice view on the balcony outside the apartment unit. Nice Turkish takeaways around the area.
Cons: Tricky shower -- either the water is too cold or too hot -- difficult to find the perfect warm temperature (tip to future guests: it's not in the middle, it's somewhere on the left at 07:00 angle, you need to move it for 1 or 2 millimeters and check first until you find that perfect angle). Bathroom sink I think was clogged since the water fills up and takes time to go down. The room smells like cigarettes -- I smoked myself but I did it outside the apartment on the balcony -- perhaps a deep scrub of the room and make it a rule that guests should not smoke inside the room.
Note: I cannot comment on safety since I just walked around the neighbourhood on my first afternoon and took the taxi most of my stay. Though I noticed there are some alleys you need to walk through to get to the apartment complex that there not so much people to none and no establishments. But other than that it was okay.
Overall, it was a pleasant stay! I would recommend Kamal's place! And I would stay in this room again if I come back to London and need a place!
