This is a real "FLH" experience, the flat is perfected located and the neighbourhood of Sants, has his own history and heritage, so you will enjoy a rich local life with much less mass tourism. I highly recommend to explore the surrounding, shops, restaurant, boulangerie and patisserie … one tips try Kessler & Galimany on Carrer de Sants :)
The appartement is only 1 to 3m walking distance from Metro, Bus, Train etc and with the "TMB" official Barcelona transport app it will help you for moving around friction less.
Thanks you very much Pau our two weeks stay were perfect and we will come back.
An immersive happy experience into the fantastic life of Barcelona :)
