My friend and I loved staying at Vivian's place in Barcelona. It's an easy walk to many of the best sites in the city and right by two metro stops. The airbnb is great to come back to relax in, especially the beautiful terrace. It's also right next door to a grocery store, which was great for stocking up on what we needed for our week long stay. Vivian was super responsive and helped us with whatever we needed (including finding where we could find easy, convenient covid testing sites). I highly recommend you stay at Vivian's place if you are travelling to Barcelona!
