Tldr: Our single night in the cottage was adequate enough given our brief stay, but I would not stay another night.
There were many issues that needed either significant repair - the ceiling has multiple peeling patches; cosmetic fixing - the walls are chipped and second rate construction work; there is no fan in the bathroom, but also it is not closed off from the main space, so whatever you do in there you share; or cleaning - lots off dust, grime, a low key weird smell in general, and then the bed area on the left side smelled faintly yet persistently like puke.
To its credit, the garden is beautiful and from what I could tell of the house, it was well decorated and maintained. The main house’s kitchen was lovely and there is a meditation space. Did I mention free parking? Plus it was in perfect location close to the airport and popular districts.
Now, if you’re the kind of person who doesn’t mind where you sleep as long as everything else adds up, the cottage will be a great fit. I however spent my time in the cottage uncomfortably.
Review-wise, those who stayed in the house seemed pretty content, those in the cottage, not so much and despite the host saying those issues had been addressed, I saw obvious indicators that it wasn’t, or done so poorly. There is lots of potential though, so I hope it gets the polish it deserves.
