We showed up on Friday around 5 or 6 and had a very difficult time finding parking. We circled the block about 6 times before finally finding someone that was leaving. We decided to leave our car there till Sunday rather than use it.
The house itself was really pretty and the directions to get to the treehouse were easy to follow. The treehouse is not really a treehouse, it's in the backyard up some stairs with a tree around it. We saw other people sometimes passing through, but if I never saw them, I would have never known they were there.
The room itself was small, but I didn't feel like it was too cramped for two people. The bed was comfortable, but we kept ending up in the middle of the bed throughout the night. I couldn't seem to stay on my side. There was little privacy for going to the restroom as mentioned, but if you have to go number 2, just send your guest outside for a bit :)
The planes go by about every 10 minutes depending on the time of day, but it really wasn't that bad at all. They do provide earplugs, but I got used to the noise pretty quickly so they weren't necessary.
The shower was really neat and heated up quickly, BUT there was a sharp stump sticking through the side of it... my bruise from hitting it is finally going away after about 2 weeks. Make sure to cover it with a towel or something beforehand.
The only thing I was disappointed with was the view. The description and the pictures show a really nice view from the private deck, but it seems that too much foliage has grown since those pictures were taken and we couldn't see a thing through it. That was definitely a bummer as we were looking forward to that.
The walk to Little Italy was very short, maybe about 10 minutes. We loved all the restaurants and places to see nearby. There were several homeless people on the walk to it though, so if you're uncomfortable with that, I recommend taking an Uber.
All in all, I'd probably stay again if the view was better.
