The apartment is extremely close to the Barcelona Sants train station, about a 7 minute walk and Lijie was wonderful at showing and sending us all turn to turn directions and photos to show how to get from the airport to the apartment by train. It is also very easy to get Uber and mytaxi here and from the airport to her apartment, it was about 20-30 dollars depending on the time of day. Near the apartment, there are lots of supermarkets for quick grocery shopping and many different restaurants and cuisines. Apartment is very safe and has several locks , which made us feel more secure and the apartment building itself is also very safe. Wifi is very fast and at night, there is some street noise, but if you put the shutters on the window, no noise is heard and the shutters also keeps the light out. As we were checking out, a cleaning crew came in and quickly removed all the used sheets, pillow cases, and towels and put them in the laundry in the apartment itself which was a big relief to know that they do in fact clean everything. If you are going to book a “Bus Touristique” tour, which I recommend, there is a stop right across from the Sants station, which is only 5 minutes away so we can hop on and hop off very close to the apartment. Lijie graciously accepted to hold our luggages before our flight time (which was after check out) and for early luggage holding when we arrived before the check in time. Would definitely stay here if we visit Barcelona again due to the security of the apartment building and the ease of travel that the location provided us with.
