Customer service was kind.

Rental was ok, Customer service was so so bad!
I went earlier than my booking time, and asked to finish the paperwork in the meantime (since it was my first rental), the receptionist refused, very rudely, and preferred to stay idle, and let me wait for 40 minutes, than to take a head start with my paper work. Then some customers arrived after I did, with an even later booking time, and she preferred to handle them first before handling me.
Then, she finally started handling me, after my start time have passed!
She gave me the wrong car from the wrong class, claiming my car wasn't there,
When I went to the parking, I found that my car was indeed there,
So, I went back to her, and asked to have the car that was in the booking originally, she said it had a flat tire, which didn't seem to be true, because I checked the car, actually, and it didn't.
She was just rude to me for no apparent reason. Kinda ruined the experience. Especially for a new customer!!
I'll think multiple times before I go (or advise anyone to go) with Sixt again!

I'm thankful that I eventually found an apartment through Wunderflats, but it hasn't been easy nor straightforward.

I have applied to tens of flats, and most of the landlords/ladies didn't even reply, many rejections without reasons given, and many of those who replied said that their apartments were actually not available, but they forgot to update it on Wunderflats.
Meaning: Many of the offerings were out of date.

Also I don't like the fact that Wunderflats generally discourages potential tenants from viewing the apartment before signing.

User experience wise, I would have appreciated a filter to filter out apartments that I've already seen, or applied to.
Or even sort them by ad creation date, so I could see the newer offerings.
