Luis was very responsive & communicative, and the room was a reasonable price for the location and proximity to the tube stations. The room was pretty spacious, and comfortable. The neighbourhood was generally quiet with no loud noises at night. The single bathroom is shared with a few other guests.
There are no lifts and about 6-7 short flights of stairs to reach the apartment, so it is recommended to carry a light luggage.
I would also recommend travelers who would be using self check-in to come in the day, as it may not be so easy to find access to the house and room keys at night.
Overall, I would recommend this place as it is a fairly affordable stay by London standards. Luis is also very helpful and would be quick to address any queries you have. :)
