What most needs comparing here are the 14–15㎡ semi-double rooms, the 19㎡ standard double rooms, the 23㎡ standard twin rooms, and the 30㎡ triple rooms with a bathtub. There are quite a few room-name categories such as A, B and EX, but if you are only staying one night, the first step should still be to look at bed type, size and bathroom form, rather than rushing to understand every letter. Some 14–15㎡ room types have only a shower, which differs from the needs of someone who wants to bathe in the room.

If two people can share a bed and do not have much luggage, a 14㎡ semi-double room or a 19㎡ double room may be enough; I would place the 19㎡ room in the scenario where a bit more space beside the bed is needed. If friends travelling together each want their own bed, the 23㎡ standard twin room is more sensible. For three travellers, the 30㎡ triple room has three single beds and its room type states a bathtub, balancing separate beds for rest with bathroom needs, without cramming a two-person room into living space for three.

Reviews show two sides to sleep quality: some people find the rooms clean and staying a night before or after a flight very low-effort, while others find the semi-double rooms rather small or feel their rest is affected by air-conditioning noise. This reminds me that if I only stay a few hours, a comfortable bed and quiet matter more than the view; if I stay several nights in a row, I should not pick only the smallest semi-double room.

Standard Semi-Double Room | 14–15㎡, One Double Bed

For this room type, I would first look at the number of fellow travellers and how they sleep, then compare the actual room price, space beside the bed and number of luggage items together. Room types with similar names do not necessarily have the same beds or bathroom; small double beds, standard double beds and large double beds are different configurations, and you should not treat them as sleeping the same just because they say “two people can stay”.

Standard Double Room | 19㎡, One Large Double Bed

If two people each need stable sleep and room to move, I would compare this specification with the previous one on the same page, rather than only looking at the first price shown on a booking platform. When travelling, needing to open a suitcase, organise shopping bags or work means differences in size often affect use more than furniture colours do.

Standard Twin Room | 23㎡, Two Single Beds

When the number of fellow travellers grows or luggage increases, I would first confirm whether this type’s actual number of beds and bookable occupancy match. Whether each person can rest comfortably at night on a trip matters more than booking a room that looks cheaper on the surface but actually forces sharing a narrow sleeping space.

Triple Room | 30㎡, Three Single Beds and a Bathtub

This type clearly differs in known size or bed configuration, so before choosing I would consider sleep habits, luggage space and length of stay together. A larger room suits people who want to reduce disturbance from sharing, but whether it is good value still depends on the actual price difference, not just the word “premium” in its name.
