We had booked a two bed apartment with four single beds. On arrival we were given an apartment with bunk beds and a double bed. After complaining to the owner, and some discussions, we were offered another apartment which had a double bed, single bed and a sofa - not what we had booked but we had to accept as there was nowhere else to stay at such short notice. Luckily, it was for only one night.
Also, the shower didn't work properly.
