The apartment itself was lovely; clean, quiet, comfortable, in a great location, with plenty of space and good cooking facilities. We did encounter a number of issues however.
Note that for these inconveniences, the host was kind enough to give us an 11% refund.
* Firstly when booking, I asked if synthetic bedding was available as I'm allergic to feathers. I had to ask a couple times and was told to ask again just before our stay so that the host could get someone to check. As messages were being automatically translated between English/German, I assumed this to mean they would sort it out at the time... turns out this was not the case, and I found out the bedding was not suitable just as I was travelling. I pleaded with the host to find some suitable bedding but their initial response was No. I contacted Airbnb, who were sympathetic and formally requested the host to sort out bedding. The host then delivered synthetic bedding along with the keys to the apartment; I'm grateful that this was resolved, but frustrated that I had to complain for it.
* On the second day of our stay, the toilet flush broke. We had to resort to flushing manually with jugs of water for our entire week-long stay, as this was only resolved on the morning of our check out!
* There are exposed wires in some of the electrical outlets and lighting, it's possible they are disconnected but I didn't try to find out!!!
* We were only given one key to the complex, which was frustrating as we often had to wake each other up to get back in after a night out.
Some things that weren't big problems for us, but good to know:
* Others have mentioned the check-in process is difficult, we had to wait outside for 30 minutes for the keys to arrive via taxi (we arrived during rush-hour), and then another 15 minutes to be let into the complex as the doorman was absent. To be honest, this seems preferable to the broken old automatic system!
* The complex is very quiet, but there are no internal doors between you and your other guests - so bring earplugs.
* The only toilet is indeed accessed through the master bedroom.
* You need to hold the microwave door closed for it to work.
* To unlock the front door, you need to pull it towards you while turning the key.
* Be careful of the chair in the master bedroom, it is broken and will probably collapse if you sit on it.
The host aware of these issues, and says they will make improvements for future guests.
