Guys, I will break up my review into 2 parts - the flat itself and the "service provided"
1. The flat itself is not bad and I could say it's actually pretty good. Apart from the dirty couch, not correctly functioning drainage system in the shower, 5x slower than advertised internet speed, washing machine not working initially and a missing trash bucket - it's fine. Now for the good parts: The flat has two big screen TV which are great, it is really quiet and the location is good. It also has a nice big terrace and an air conditioner in every room which are also great.
2. Now for the "service". To say the least, we were unsatisfied with how the "manager" of our apartment handled our stay. First of all - she did not respond after 8 pm - at all. Second - the internet at our apartment was supposed to be 50 Mbps - it's actually 7 Mbps. When we wanted to extend our stay further at the last day- our time ran out to do it properly on AirBnb since the "manager" doesn't reply to message in the evening. The washing machine in our apartment wasn't working and we had to resolve this issue with our "manager" - well to be fair they did resolve this issue during 24 hours, so kudos to this. Anyways, the communication was not good and we were not offered any compensation for our troubles here.
