All pots and pans had to be thoroughly cleaned before we could use them for cooking. The frying pan was of no use as it does not work on an induction hob.
Kitchen sink and shower were very badly clogged right from the start. Luckily someone came to fix it quite quickly.
Checking in and out should be improved : the hosts should not have to ask the day before the arrival how to get the keys and how to access the flat and how to return the keys upon departure - without getting an answer for the latter.
Communication should be improved : no answers to 2 of my mails re: a change in the booking and the check out procedure.
The building is basically in the middle of a roundabout and you can't open the windows because it is too noisy - the flat is on the 6th floor.
However the flat is bright and modern but the experience could have been much better.
