I had a great stay at Layla's apartment!.
The place is exactly as shown in the listing.
Communication with Layla was always great and almost instant.
The self check-in was really easy. Layla sent me the instructions a day before, and since I had to pick up the keys from a lockbox, it's a great option if you have to arrive early or late in the day. The apartment is at the 3rd floor, and there are only stairs. It wasn't a problem for me since I had a medium size bag.
Location was also great, there are a lot of bars and restaurants nearby, and a supermarket at 100 meters from the apt. The Overground is also really close, maybe 5 min walking (or less), and also 10 min walking from the Northern line. There's also a bus stop at the other side of the street. Since there are a lot of bars, you can also expect a lot of noise from outside on weekends (maybe until 2am), but this also wasn't a problem for me since I always go to sleep around that time.
Inside the apartment you can find everything you could need for the stay. The kitchen was really complete, everything worked great. There's a big fridge, and a washing machine.
The bed was really comfy and big, with a lot of pillows. The bedroom is big enough to leave your things there (there's also a wardrobe).
The bathroom was also very nice and clean.
Bonus points for free Netflix and fast Wifi!
I would definetly stay again next time I travel to London.
