This is a fabulous little space, but emphasis on LITTLE! I definitely would say no more than 2 adults, honestly. We had myself, my husband, and my 3 year old. We use an inflatable toddler bed when we travel and it BARELY fit between the foot of the bed and the closet. I had to squeeze it a bit. Before I set up the inflatable bed I opened the closet just out of curiosity and unfortunately they have two very heavy mirror doors that are broken and don't slide. we didn't need the closet space so that was fine but I was very worried about the safety issue having my toddler sleep right next to it, but we didn't have much choice. Luckily it was okay but I would recommend having those doors fixed before having another small child stay in the room!
We also pretty much only used the space to sleep at night because we doing all the tourist things during the day! This meant that we didn't mind that our suitcases took up all the space in the living room and on top of the couch. But if you wanted to actually chill in the living room you'd probably have to move your suitcases back and forth each time. There was definitely no room in the bedroom for them!
Also the blinds were really hard to open and close, and they were covered in dust :(
My last recommendation would be to add a keychain to the house key, it's a small solo key that I was so worried we were going to lose!
Another tip is to add instructions for how to use the AC, we couldn't figure it out when we arrived late at night the first night, and even the next morning it took some figuring out!
But honestly these are all nitpicky items. The place was immaculate, with more than enough supplies for whatever we could need! The pathway was gorgeously lit for when we arrived at night, the yard is so beautiful, and we even enjoyed the deck for a bit. We especially appreciated the child Brita water in the fridge!! Even though it was small it was perfect for what we needed and we'd totally stay again!
