Lijie is a very gracious and an excellent host, She helped us out and answered every question we had, even though we arrived before check in time she was gracious to help us out & open up her apartment for us to store our luggage. Location of the apartment is just perfect, Centrally Located - Sagrada Familia, Casa Mila & Picasso Museum within 10 - 15 min walking distance of the apartment. Tetuan Metro station within a 2 minute walking distance, Girona Station within 5 min walking distance & Arc de Triomf with 10 min walking distance. Metro is very easy to use, If you are in Barcelona for more than a day & visiting all the Tourist Spots- I would recommend buying a T10 Metro Ticket from the Automatic Vending Machine which also excepts Credit Cards. Note of caution if you plan to use US Credit Card - All of Europe does not use Credit Card Scanning which means the Credit card should be a Chip Enabled Card with Pin Access. Make sure before you leave US that the Card has a 4 digit Pin assigned as certain location requires you to enter 4 digit pin - Ticket Vending Machine at the Metro stations is one of the location. The Vending Machine has English Language option available by clicking on a Symbol of British flag, Ticket can also be bought from the manned ticket Window, although we noticed that the ticket windows were only occasionally manned.
T10 ticket is much cheaper than buying individual tickets- T10 gives you one ticket with 10 Metro rides which any one can use - We are a family of 5, so each day we used 5 to go & 5 for return - this 10 ride metro ticket can get you to your destination station as long as you stay within the Metro & do not exit the Station until your reach your destination station, If you plan it properly & study the Metro Map - you can reach your destination with several transfers using one metro ticket per person.
There is a supermarket just below the building where you can buy some groceries & daily needs.Pharmacy is also within 2 minutes of walking

This is an awesome and a very spacious apartment, in a very safe neighborhood.
If any one requires more information on Barcelona or anything in general 'am happy to provide one
