I was disappointed and outraged.
Firstly, the address was wrong and I had to wait for 30 min outside for the host to reply.
Secondly, I felt unwelcomed. No one introduced themselves to me, and it was the host's girlfriend who showed me in. The amenities were okay, the room clean, but the water for the shower was cold. I like my showers burning hot, so it was a real downside for me.
Thirdly, there was loud music playing all along which I didn't mind until I went to bed around 11pm. There threw a party until 1am and no one warned me about it, nor apologized in advance for the inconvenience. Finally, I went finally managed to fall asleep people kept coming into my room. At 1am some random guy from the party entered into my room, having forgotten I was there... That was unacceptable.
It was probably bad timing for me, but the least they could have done is warned me and apologized, which no one did.
