It's quite nice that the host allows me to check in early (That's why I added back one star). However, other than this, I couldn't really list out any other merits.
This is a pretty small (fine for solo traveler given its price) and dim (completely opposite to what's shown in the picture) room that is probably 1/3 underground, so you see pedestrians' feet through the window.
The room is extremely cold. Even if the radiator is turned on, it could barely heat itself to lukewarm and the host sometimes turns it off without notice. The bathroom is even colder because the radiator is completely turned off and the window is usually open. The hand soap is super diluted. Hot water is indeed hot though.
There is no Internet throughout my 5-day stay.
This location is convenient for a metro and a bus connecting to the popular attractions, but this is definitely not a well-developed neighborhood. Just because the city itself is not big, the transportation doesn't take that long.
