I booked this stay for four adults in their mid-20's and can say that this should be for 2 adults and 1-2 small children if you can deal with the noise from upstairs guests.
The overall location is great and the space is nicely redone in terms of look, feel and updated appliances. The two big things we had an issue with was the noise from upstairs and the twin beds being a trundle that couldn't be split out into two beds.
Unless two people are willing to sleep on a pull out couch mattress, this air bnb should not be advertised as being able to sleep four normal size adults comfortably. The twins are attached together, one on top, the other pulled out from underneath it. They are also in a small room with curtains and glass doors that you can see through both. No privacy at all for the people staying in this room.
Additionally, the noise from the people upstairs is such a bad situation. The people upstairs were never talking or doing anything extra loud but you can hear everything they are saying at all times coming from the door I am assuming is a staircase upstairs to the other air bnb. Our friends staying uncomfortably in the twin beds also had to deal with the noise of the upstairs guests all night as they came back at 2am. Again, they were doing nothing wrong as they were simply talking at a normal sound level, but we could hear everything. The main bedroom was great except the noise issues as well. Any time someone upstairs goes to the bathroom, it sounds like a waterfall is coming into our room. I was woken up twice from this super loud noise.
Would probably book the upstairs airbnb if choose to stay here.
