Going to start with the positives!
Location: 5/5. So easy to get around as the station is right there for both the underground and National rail service.
Heating in the house: 5/5
Ventilation in the twin bedroom: 5/5
Kitchen: Extremely well equipped 5/5
Wifi: 5/5
Suraj is also very easy to contact and responsive and was able to sort out a small issue we had with the shower.
There's a Nepali restaurant below that can store your bags for a small fee which is great. Be mindful they open at 12 and close at 3 and open again at 5ish so you need to manage within that.
Now for the cons:
Given the total price we paid (nearly 60 per night, my friend and I did not feel it was worth it. I do also think that we received different room than the one advertised.
The place itself lacked a personal touch and was worn down.
The bedroom was clean but beds were not very comfortable. (2/5)
There is one bathroom with a tub, 1 with a cubicle shower and 1 toilet to be shared with 4 rooms (if you're unlucky then 6 other guests) so they're not going to be clean at all times.
The inside of the toilet WC were terrible with this coating of rust that frankly made me wanna run miles. In general I'd give the toilets 1/5 as I used public toilets on my trip that were far cleaner. They need bright new lights, a revamp and a professional deep cleaning. The wash basin mirror in the main bathroom was missing too.
The check in process doesn't allow for much flexibility, if like us you travel to London on a whim and aren't sure of your timings. Perhaps a lockbox with a code would be nice so we can check in anytime after 2 instead of trying to coordinate with the hosts schedules and ours.
