I'll start with the good stuff: It is a gorgeous apartment.
Unfortunately, the electronic locking on the door failed the day we arrived, after we'd checked in and dropped our bags, so we ended up locked out of the apartment with a toddler at night.
The hosts didn't answer their phones for two hours and we eventually regained access around 11pm.
Whilst they did provide keys after this for the flat door and the outer door of the building, we never received keys for the gate.
I received very little apology for the issue with the locks, especially given that I had a child with me, and there appears to be no contrition on the part of the hosts.
There was no house manual, which was frustrating, and the remote for the TV did not work.
