As my flight UO614 arrived incheon at 2:30am, there is no free shuttle bus in the midnight, so I take the taxi to the guesthouse which costs 5000w( better to print the map and ask the driver for the fee before get on the taxi)~
The hotel is clean and comfort.
There is a check in late charge for arrival after 1am which is not written on the expedia website! And they just inform you 1 week before it, so its better to ask clearly once after booking, so u can have a better plan on amending the booking if neccessary
Luckily after email with the guest house manager Mr. Choi, password and room number can be given on the arrival date, so no need to do the check in in the mid night and the late check in charge is not applicable.
Afterall, the stay in the guesthouse is good, i will still recommend it to people who have early or late flight to incheon and want to take a good rest. The price is reasonable.
