Great apartment in a central location just outside the tourist area (which is a good thing). Very clean place & extremely helpful host. Wilkin met us at the apartment & answered all our questions as well as providing maps. Highly recommend the bus tour that you can hop on & hop off. I don't like guided bus tours so this was perfect to see the city. After the bus tour on Sunday we spend the next four days walking & exploring the areas we saw & liked while on the bus.
If you don't speak Spanish I'd highly recommend learning some. We did ok but it's the only regret from the trip. It would have been a much richer experience if we could have interacted more with the people, bartenders, servers and workers in the shops.
Also Las Ramblas is the tourist place to visit but we loved all the different neighborhoods and their shops & mercats. The Picasso Museum was amazing. The audio tour is worth the extra $5 euros. Over all loved Barcelona even in January.
