We stayed here on the last night of our stay in Jeju, as we needed to be near the airport after returning of rental car.
They have valet service for cars; the hotel room is spacious and clean plenty of dining options nearby (hotel staff recommended us but we decided to take the car for a drive to black pork street before returning).
There is a weighing scale at lobby - great for us trying to figure if we are overweight.
When the central AC was a bit warm - we just called frontdesk and they turned on the AC blower unit so that was perfect.
Just to say - this hotel is a 20 mins bus ride from Jeju Airport (the taxi queue was CRAZY) and so we just hopped onto bus for 1150 won /pax - bus stops right across from Hotel Leo.
Next morning, hotel booked me a taxi and it was 5500 won / 10 mins ride to airport.
Please do consider staying here if you need a convenient spot in Jeju City! I can't wait to be back - Thank you Hotel Leo!
