One Perfect Day in London

My Quick London Stopover

After leaving San Diego early on Sunday, at 9:00 AM, we flew to Boston and then caught our overnight American Airlines flight to London. The Boston AA Lounge wasn’t bad—it had decent snacks, coffee, and some space to relax before the long flight.

Arrival: Monday – London – 6:00 AM

We landed in London early in the morning and decided to store our luggage at the airport before heading into the city. There’s a baggage storage service right near the arrivals exit, and while convenient, it was quite pricey—£15 ($20 USD) per bag, but worth it to travel light.

We took the Piccadilly Line toward Piccadilly Circus, but mid-way we found out the line was under construction and didn’t go all the way. So halfway through, we switched plans and called an Uber to Piccadilly. London’s Uber prices were surprisingly reasonable.

Morning: Exploring Central London

We started our self-guided walking tour from Piccadilly Circus, admiring the architecture and buzz of the city. From there, we walked toward Buckingham Palace. On the way, we stopped for coffee and dessert at a charming café and also popped into Fortnum & Mason, one of London’s most iconic luxury tea and food shops. It’s a must-visit for anyone who loves gorgeous packaging, British teas, and elegant gifting.

At Buckingham Palace, the area was absolutely packed—it was a Bank Holiday, and something special was clearly happening. Still, we soaked up the energy, took photos, and enjoyed the classic London moment.

Midday: Sloane Square + Brunch

From Buckingham Palace, we grabbed a taxi to Sloane Square, which is such a pretty area to stroll through. Upscale and charming, with designer boutiques and peaceful side streets.

For brunch, we chose Ottolenghi in Chelsea—an absolute treat. The food was fresh, creative, and delicious, especially if you love Mediterranean-inspired dishes. Their pastries and salads were heavenly, and the vibe was stylish but relaxed. Definitely one of my top spots in London.

Afternoon: Harrods + Coffee Stop

After brunch, we headed over to Harrods to take in the iconic department store. Even if you’re not shopping, it’s worth a visit just to browse the food hall, beauty counters, and seasonal displays. It’s luxurious, beautifully decorated, and filled with fun things to explore.

Before heading back to the airport, we stopped for a quick afternoon coffee, took a breather, and called an Uber back to Heathrow to grab our flight out.
