This apartment is located near the Sagrada Familia (a few blocks away), and within walking to distance to the Passeig de Gracia shopping area and restaurants. There are a couple of markets within a block or less. We were able to walk to most of the attractions such as The Picasso Museum, Sagrada Familia, and even walked up the hill to Park Gruell (it's a hearty walk, but doable.
There are many restaurants within walking distance such as Cerveceria Catalana or its sister restaurant Ciudad Condal (you'll see the same menu at both). We went to both and recommend at least 1-meal there. We spent 5-nights here and wished we could have stayed 10.
The apartment had plenty of room for our family of 5-people. And having the convenience of nearby markets, restaurants and sites to visit makes this apartment a great place to stay. If you like shopping the luxury boutiques on Passeig de Gracia, it's a 10 minute walk with many great cafes along the way.
The one thing we would want improved is the wifi strength. It could be spotty in some rooms, but we managed for the most part. We contacted Sito about the wifi and he sent a maintenance person who tried to fix the wifi while we were away. The connectivity slightly improved in the troubled area (living room) - perhaps relocating the router may help.
Communication with Sito and his team was excellent. All done thru the Airbnb app and without any hassles. His team is professional and will take care of you and any issues you need resolving.
