stayed with 5 friends. the space was very big and could comfortably fit us all. beds were old but did the job, awkward choice of paintings on the wall, many of which were hung upside down, PC monitor for a TV (which didn't work).
on to the more pressing things which made our stay unpleasant:
the living room ceiling was leaking brown liquid on the morning of our second day.
there was only hot water on the first day of our 4 day stay.
WiFi was so spotty that it was unusable.
very loud bar right downstairs that partied till 3~4am nightly.
dark and sketchy staircase leading up to the unit, which had a door that didn't lock properly.
the host was quick to try and resolve some of the issues, but necessities like hot water were not resolved and it was impossible for us to shower during the cold nights.
very hard to paythe tourist tax by card as they only accepted an international bank transfer (which seemed sketch) and rejected our 200€ bill on claims that there were many instances it was counterfeit. I mean, we're on a holiday and changed our cash prior to the trip and received notes in dominations of 200s - why make our lives harder by rejecting it and forcing us to go through a bank transfer? you can do better. get a POS system or something guys, it's not that hard.
I do not recommend this place as 1) it isn't particularly cheap, 2) per my list above and 3) unless you're planning on spending a lot of time within the Airbnb with your group, split the group up and get a hotel as it'll probably be a lot more comfortable.
