Our planned 3-day stay in this apartment, lasted only 15 minutes... upon arrival at the apartment building, we were met by a huge construction site, which right from the beginning set off big red flags and also set the tone for the rest of the experience. The construction site extended into the apartment building, where we had to climb very filthy stairs (the elevator didn't work), walk down a very unsafe corridor (where the floor seemed to cave in at any given moment) and finally entered the apartment, where all the windows were covered by metal construction grids and the air was impossible to breathe in. We felt very unsafe and were therefore force to move to a hotel at the last minute, which made our stay in London twice as expensive.
Overall very very disappointing and saddening experience and I would truly urge the owner to update the description of the apartment to include the circumstances surrounding it, as I certainly wouldn't have booked this place had I known this information.
