It's a great location - we liked the subway proximity and an option to get on foot to many attractions (Park Guell, La Pedrera, Casa Batllo and Sagrada Familia are 25 minutes away, Casa Vicens are 5 minutes walk). There are many nice cafes and restaurants within 5-10 minutes walk as well. At the same time it's quiet, and the terrace is very pleasant.
The downside is the apartment itself - it needs renovation, many smaller things like light switches, door handles, terrace floor, cutlery etc. are in fairly rough shape - it's not a dealbreaker, but I expected better conditions for the price.
