Great place and space is more than enough for 4 people. Value is absolutely amazing for 5 nights, which (including the cleaning fee) came up to about a little over 14k in local currency. Stayed an extra night which cost me an extra 3k - the cleaning fee being half of it - so I recommend booking for more than two nights to get your money's worth. The entire building is an airbnb as far as I know, and the second floor (which is where I was staying) had see through containers of all the necessities if you needed extras - including bed linen, towels, packs of tissue, and toothbrush + toothpaste packs.
The airbnb itself had prepared two hair dryers, five towels, and five toothbrush and toothpaste packs before my arrival. It also had two bathrooms (one in the master bedroom), and had hand soap, shampoo, body wash and face wash in each bathroom. The kitchen had basic cutlery and dishes to use, as well a basic set of kitchenware (pot, pan, etc...). Surprisingly also included a corkscrew which was great since I forgot to bring my own. Fridge was a little small but doable. There was no washing machine or dryer that I could find within the unit's vicinity or right outside it's door. The only complaint would really be that the walls and floors are thin enough to hear other people (either that or the other Airbnb residents were too loud). Wouldn't hold it against the host since both the floor above me and below me were celebrating birthdays a day apart - so lots of shouting (did not contact the host about this at all when she contacted me during my visit inquiring about my stay since, ya know, it was two someones' birthday celebrations and wouldn't want someone else doing that to me). Considering how picture worthy and spacious the host's units are, I wouldn't put it past that party celebrations are a common occurrence in the building. No elevator so keep that in mind, and if you take an Uber/ taxi there, have them park right outside the lane instead of driving in since its a bit cramped for bigger models.
(Spoke and texted with the host in Mandarin so I can't comment on their communication skills in English)
