The apartment is conveniently located near many shops and restaurants (within 1-5 min walk). Grocery stores located within 1-5 min walk to service all your needs.
Gracia is a very authentic neighbourhood and less touristy then the heart of the city which makes for a nice break from the hustle and bustle.
Taxis can be found on the street directly outside of the building and range from $10 euro to take you to the cash mila area and $15 euro to the water front. Depending on traffic these are 10-25 min commutes. If your ambitious you can walk to Casa Mila in 25-35 mins and to the water front in about an hour.
Apartment was very clean and updated. Kitchen had all the necessities needed for my 10 day stay. Blackout curtains were an added bonus.
The only minor thing that did not make the apartment perfect was the hard mattresses.
Overall I would highly recommend this apartment for your stay in Barcelona.
