Unfortunately, it wasn't mentioned that we would share the apartment with a dog. The situation would have been much dire if one of us were allergic. Also, our room was separated from another, therefore it appeared much smaller than what you can see on the pictures of the announce.
We couldn't go to the balcony without smelling the dog, who was also very intimidating. There weren't any other way to let air flow into the rooms.
Harold was very nice, but it's a shame he had to enter the room twice a day. At this price, it would have been appreciated if we could have been notified about all of that.
We were also a bit disappointed about the bikes we ranted from the host. They were a bit clunky.
Apart from all that, Harold was very very nice to us and very communicative. The room was clean and comfortable. It would have been nice if we had been warned about the dog and the separation between the two rooms before hand.
