I experienced problems with the apartment and the company handled each of the problems badly.
First, the key to the building did not work. I was told multiple times to just ring somebody else in the building to get in. I had to follow up with the management company 4 times to get them to take the issue seriously and send me a new key.
Second, the heat was not on when I arrived at 9:30pm. It was London, in January. It was freezing, too cold to shower or even sleep. It took hours for the heaters to warm up.
Third, there was no hairdryer, even though it was in the listing. They ignored me the first time I brought this to their attention. When I followed up again, I was told that it would be faster for me to buy one myself and get reimbursed. So each day, I had to wait an hour for my hair to air dry before I could start my day.
Based on these and other discoveries around the apartment, it seems clear that it is mismanaged and nobody is checking the apartment in between people.
