Bangkok, first time: which neighbourhood to sleep in

Short answer: in Bangkok, where you sleep is really "which station" — the traffic is bad enough that being a two-minute walk from the BTS or MRT beats being next to a temple. For a first visit, base in Sukhumvit (around Asok) or Siam: central, on the train, and walkable to food, malls and the interchange. Then pick your exact spot for the evening you want.

The one trap to know up front: the old city, where the Grand Palace and the temples are, has no BTS or MRT. It's the most atmospheric area and the worst-connected — sleep there and you'll spend your days in taxis crawling across town. Base by a station and visit the old city by boat instead.

The two safe first-timer bases

• Sukhumvit (around Asok / Nana / Phrom Phong) — the default. The modern city's spine: the BTS and MRT cross here, so you're one ride from anywhere, and the street is wall-to-wall food, rooftop bars, massage and malls (Terminal 21 sits right on the Asok interchange). Every budget, from hostels to five-stars. The easiest first base, and hard to beat.
• Siam — the shopping heart, dead central. The BTS interchange and a cluster of giant malls, a short hop from everywhere on the Skytrain. Less nightlife than Sukhumvit, more daytime buzz — a tidy, central pick if shopping and connections are your thing.

The other areas, and who they're for

• Silom / Sathorn — business by day, lively by night. On both the BTS and MRT, close to Lumphini Park ＋ and the river, with rooftop bars and the Patpong night market ＋. Corporate in daylight, buzzing after dark.
• Riverside (Chao Phraya) — the grand hotels and the water. Bangkok's most beautiful stays line the river, near ICONSIAM ＋ and a boat-ride from the old-city temples. Romantic and calm, but a little removed — you'll lean on the hotel shuttle boat and the pier at Saphan Taksin to reach the BTS.
• The Old City / Khao San — atmospheric, backpacker, off the train. Steps from the Grand Palace ＋ and Khao San Road ＋, cheap and full of character — but with no Skytrain or subway, getting anywhere else means a taxi or a boat. Best for a short, temple-focused stay or a tight budget.
• Ari — local and leafy. A few BTS stops north: a residential, café-and-brunch neighbourhood with little tourist crush. The pick if you've been before and want to live a little more like a local.

A few notes

• Book within a couple of minutes of a BTS or MRT station. In this city, the walk from the platform beats the neighbourhood every time.
• Two-plus nights in one base. Bangkok is a one-hotel city — hopping just feeds you back into the traffic.
• Riverside for a treat, a station for the rest. If you want one splurge night by the water, take it — then move back to a train-side base for the sightseeing days.

The mistake to avoid

Booking next to the Grand Palace because that's what you came to see. The old city is gorgeous and cut off from the train, so a temple-side base quietly costs you hours in traffic. Sleep by a station, visit the temples by boat in the morning, and the whole city opens up.

Working out which base actually suits your days — every candidate weighed against your real stops, station access against the traffic — is an evening of tab-switching. We do about 80% of that research for you, in roughly a minute. Tell us your dates and we'll build your Bangkok days — routed on the real BTS, MRT and boats, each day kept to one part of town so you're not crossing the city in the heat, then let the plan pick the base. A solid first cut you can run with.
