Gonna be honest here.
So starting from barking area... I felt like I wasn't in the UK once I stepped into it.
Receptionist flirting to me straight away and offered to show me the room after I done check in. First red flag as a female travelling solo, once I refused he started been cold to me. People shouting on the corridors.
I came back from concert and arriving to my room front room had loud TV at 01am, had a bad gut feeling so I grabbed my stuff and left. Way down to reception was a woman arguing with night receptionist. Loud and not nice, given my card and left the hotel. It's cheap yes, but if you are a normal person looking to chill even one night in London just spend some more money booking a better place on a safer area, barking isn't safe night time.
Also room has no window, there was a piece of wood instead, felt claustrophobic.
