Day 1
Arrived at BCN and took a shuttle to the city (one can take a bus or taxi; we took a bus and bought tickets at the airport).
Checked in at our Airbnb
Went "early" to Cerveseia Catalana - a fantastic tapas place. Go early!
Strolled around Casa Batllo / Mila and Plaça de Catalunya
For Bars, can check out Bar Marsella or Negroni Cocktail Bar or Els 4Gats
Day 2
Morning visit to Park Guell - can buy tix online or wait in line there. Then took a hike to Bunker del Carmel (also great for sunset)
Lunch - ate at Billy Brunch for a casual meal.
Afternoon, option to take the Furnicular/Cable Car to Montjuic Castle
Dinner - we had a reservation at TICKETS (be sure to reserve as early as possible)
After, we walked it off around Placa d’ Espanya and Magic Fountain.
To hang out after at bars/clubs, would recommend Opium Barcelona or Razzmatazz / Moog.
Day 3
Strolled around La Rambles, Cathedral of Barcelona, Gothic Quarter, Basilica of Santa Maria del Mar, and Guell Palace
Ate at Mercado de La Boqueria - Quim de la Boqueria” and Bar Canete
Afternoon, went to La Sagrada for golden house.
For dinner, went to 7 portees, but I may recommend Suculent or Quimet&Quimet.
I think it depends on how you like to travel. I found 7 days to be a sufficient amount of time for the 4 cities I visited - was able to see the main things I wanted to see and get a lot of good food in and never felt rushed. I'm sure there are things I maybe missed in the cities I spent 1 night in and wouldn't have minded more time to explore Barcelona, but I was happy with the time I had.
I've been to Barcelona but not the others. Do you think 7 days is enough time?
