I usually prefer flats to hotels because they are more unique. This time I would have loved to stay at a hotel where I could have complained at a reception! This flat in a building with about 15 flats is managed by a company, that even appears on the airbnb website. The people at the helpdesk are very polite and try to do their best, even if their service is not flawless. BUT the only contact with them is through the Airbnb message app. No phone number, no direct contact. The night before the start of the rental I had to write them because I hadn’t received the codes for the self-check in. Once I was at the building, I found out that I had received the code of a wrong apartment. With the code for the correct apartment, I could not open the door. Only after another message, I was told that I had to pull on the door, while with the other hand I had to digit in the code. I doubt if those codes are ever changed. The apartment seemed to be much smaller than the obviously very professional photos on the website. It was cold in the apartment! I had to send pictures of the knobs at the radiators, so that in another message they explained to me, how to make the radiators work. After an hour the radiators were cold again. After a cold night and many more messages, they must have sent someone to adjust the radiators and left a fan heater, as I had requested. The radiators still did not work, so I slept with the sound of the fan heater. The windows were not double glazed as in the profile and one of them would not close completely. Together with the cardboard like door to the stairway and the equally sound proved wall to the adjacent apartment there was enough noise and cold. The location is very good, and the apartment was clean. There was enough hot water. The huge boiler almost blocked the access to the toilet seat. There was also no left luggage left facility as mentioned. I should have booked a space for my suitcase through a website. That information I only received after another message... The WiFi was fast, but I could only access it, after I used a browser, that would allow me an unsecure website. Chrome would not work. I had a complicated and unhappy experience.
