I stayed at this apartment with my mother for one week, and the another week and a half by myself. The apartment is lovely and spacious enough for two people. It was very clean and neat. Beds are comfortable as well. However, whoever's taking the lower bunk bed, be sure to slide the door over to the side your head will be at, so you don't get waken up by the sunlight that shines through the thin frosted window next to the television.
The apartment was well-equipped with almost everything you could need; utensils, electrical appliances, toiletries. However, there was no bath mat so you'd be dripping water all over the floor upon getting out of the bath tub. There was also no sponge so you couldn't really wash your dishes properly. My mother and I bought these cheap items ourselves from the nearby convenience store.
Also, do note that while there is a bath tub in the apartment, we learned from the hosts that you cannot fill the tub with water; no baths or soaks, only showers.
My biggest "problem" was the lack of a proper desk and chair. If you use your laptop a lot or you write a lot, you might find it quite uncomfortable hunching your back over the short coffee table.
All in all, I had a great stay at this apartment! The hosts were also lovely and replied my messages almost instantly. There was even a small flooding problem (I am apparently the first guest at this apartment so they hadn't known about this problem beforehand) and I contacted the hosts about it very late at night, but still received a reply immediately, and the problem was fixed within a few short hours.
I highly recommend this apartment to anyone and I hope your stay will be as pleasant as mine was!
