A capsule bed at Siam Eco Hostel with the Bangkok Skytrain visible through the window

A modern bed in the middle of Bangkok.

Siam Eco Hostel is a clean, calm capsule hostel at the Ratchathewi intersection. BTS Exit 3 is one minute on foot; Siam is one stop away. The city is loud. Your bed is not.

From the mural on our lobby wall

Stay here, near station.

We painted a train map on the lobby wall because the location is the whole point. Everything below is measured from our front door.

About the name

The eco part, honestly.

We are not going to print leaves on everything and call it sustainability. Here is what we actually do, and nothing we do not.

HABIT 01

Refill, not landfill

Drinking water on every stay. One traveller, one week, roughly twenty plastic bottles that never get bought.

HABIT 02

Shoes stay at the door

Thai house rules. Floors stay clean with less scrubbing and fewer chemicals, and the whole place feels like a home.

HABIT 03

Trains over taxis

We chose this corner because of the Skytrain. Stay here and your Bangkok carbon footprint is mostly footsteps.

That is the whole list for now. When we add something real, it will appear here first.

No surprises at check-in

Good to know before you book.

The things other listings put in fine print. We would rather you read them now than discover them with a backpack on.

01

It is a walk-up. No lift, and dorms go up to the fifth floor. Pack like you will carry it, because you will.

02

Reception runs 08:00 to 21:00. Arriving later? Message us before you fly and we will sort it out.

03

Guests 12 and over. The capsule life suits travellers, not toddlers.

04

฿200 key-card deposit in cash at check-in, returned in full when you hand the card back.

05

Direct bookings take Thai bank transfer only. No international cards or PayPal. If you need to pay by card, book through Agoda instead.

06

Quiet by design. This is not a party hostel. Great sleep, easy conversation, no foam parties.

07

Towels rent for ฿20 and padlocks can be borrowed at the desk, in case yours is in the bag you did not bring.
