First I had a problem with the WiFi: it didn't work properly. They should have checked that it worked before I checked in and not expect me to discover the problem. This was highly unprofessional and a real pain for me since I am a student and I have work to do and talk to my collaborators. They told me they could not contact the provider because it was late (the first time - Friday evening) or because it was Sunday (the 4th time). I wonder who is their provider, since all those I know have 24/7 service for such issues. I also do believe that they never contacted them even on Saturday since they never updated me on the issue until I asked again that evening. But, I will give them the benefit of doubt on this one. However, they were very prompt in sending me all those jovial messages about promotions etc and had the audacity to do so right after they dryly replied to my wifi-related request. This was downright ridiculous. What is more, the apartment is cold and they deliberately turn the heat off most of the day, without mentioning in their "house manual" how to change this setting. I did figure it out on my own eventually, since I was cold and didn't know why. Moreover, there is no lift, which is to be expected for an old building, but they never mention that the building is old and that the apartment is on the 3rd floor/4th floor (for Americans). In fact, right across the street there is a perfectly new building which I bet has a lift, so the location is not indicative of the condition of the building/apartment. Again, they deliberately conceal information, which is unprofessional. Furthermore, the bath gets clogged almost immediately (again expected for an old building, but totally unmentioned), which made me turn the water off and wait in the cold until some of it had drained. Finally, having to return the keys back to BnBBuddy at 6am (to catch my flight) carrying all my baggages with me in the dark is unacceptable. In all the airbnbs I have spent my vacations all these years, there was not a single one asking me to pick up/drop off the keys at a different location. Do I have to mention again how unprofessional this concealment of information is? Overall a very mediocre experience, which is a true shame because the location is great, the view is amazing (especially on a sunny day) and the apartment was truly very clean and well-preserved.
