We are a couple who rented this apartment for 10 days.
The owners were very helpful in getting us this apartment, and answering questions before we arrived and while we were in town. They had ready a local area map with restaurants, supermarkets etc. mapped out. Everything you need is within 5 minutes walking distance!
The apartment is relatively simple, but efficient and clean. You can find much fancier and more expensive apartments, but for the price this is a great value. It has all the necessary equipment, incl. to cook. We cooked lunch one day and dinner one day, and we made our own breakfast every morning.
There are 3 nice squares with numerous bars, cafe's and restaurants within 1 - 5 minutes walk. It is a very nice, quiet, residential area with families, kids, retirees and feels very safe.
The streets are narrow, there is no through traffic, which makes this a relatively quiet location.
There are two metro stations within 5-7 minutes walking, from where you can get anywhere in Barcelona in 15-20 minutes.
We walked from the apartment to several places incl. Parc Guell, Sagrada Familia, the Pedrera, Francesc Macia.
And when you don't want to do much you walk 2 minutes around the block to Placa de la Vila de Cracia and sit down with a beer, wine or caffe Cortado!!
Highly recommended and we would rent this one again!
