01Gamla Stan · arrive & wander
Land at Arlanda and take the Arlanda Express — about 20 minutes to Stockholm Central (check current fares at arlandaexpress.com). Gamla Stan is a 10-minute walk south of the station, or one stop on the red/green T-bana to Gamla Stan. Drop your bags — most old-town hotels hold luggage before the 3 p.m. check-in — and let the trip start on foot. Stay all four nights here: everything radiates from the old town, and you'll never repack.
Morning
Start at Stortorget, the old square with its row of famously crooked 17th-century merchant houses. The Nobel Prize Museum (Stortorget 2) sits on the square — small, sharp, and worth 45 minutes. Then walk two minutes to the Royal Palace for the midday changing of the guard (around 12:15 in summer — confirm the day's time at kungligaslotten.se, since it shifts with the season). Storkyrkan, the 13th-century cathedral next door, holds the dramatic St. George and the Dragon statue.
- Mårten Trotzigs gränd — the old town's narrowest alley at just 90 cm wide; find it off Västerlånggatan.
- Fika stop: Under Kastanjen (Kindstugatan 1) — cinnamon buns under the chestnut trees in a 17th-century courtyard.
- Österlånggatan — the quieter parallel to the tourist-heavy Västerlånggatan, with better antique and design shops.
Evening
Cross to Södermalm for Monteliusvägen, a 500-meter clifftop path with the city's best free sunset: Gamla Stan, Riddarholmen and City Hall spread out below you across the water. In June the sun sets after 10 p.m., so there's no rush. Walk down for dinner at Pelikan (Blekingegatan 40) — a cavernous 1904 beer hall serving husmanskost, Swedish home cooking. The classic order is meatballs with lingonberry and mashed potato, roughly $30–45 per person with a beer.
Where to stay
Lady Hamilton Hotel (Storkyrkobrinken 5) puts you inside the old town in a 15th-century building — from roughly $220–290/night for two in summer. Nobis Hotel (Norrmalmstorg 2–4) is the design classic two minutes north of the old town. Hotel Ruth near Odenplan is the newer boutique pick with serious breakfast credentials. All three keep you within a 15-minute walk of everything on this trip.
Bad-weather plan
Rain just moves the old town indoors: the Royal Palace state apartments and Treasury, the Nobel Prize Museum, and Storkyrkan fill a wet afternoon, and Gamla Stan's cafés are built for exactly this weather.
Arlanda → Central: ~20 min by express train · Central → Gamla Stan: 10-min walk or 1 T-bana stop
Cobblestone rule: Gamla Stan's lanes are beautiful and uneven — leave the heels at home. And the guard change draws a real crowd in July: arrive 15 minutes early for a front-row spot.
