The flat was just like in the photos, everything inside was clean. Communication with Selina was good, she responded quickly and asked if everything was alright and offered some tipps for things to do in the area. WiFi worked perfectly. The process of checking in was easy and well-explained.
The area itself is close to the City and East End areas like Brick Lane; still, it is quite dirty and run-down, just like the house itself, but that's what you get in this area. It did not affect the flat, which was very clean.
Some small remarks: The mattresses were very worn-out and if one turned on the hair dryer in the flat, one got a message on the mobile phone or even an automated phone call from California, saying that the noise level was too high for the flat. Just make sure that you are far enough from the noise detector.
Also, when showering, the water in the bath tub took a while to drain, but that is quite common in London.
Overall, it was a nice stay in a nice flat.
