This apartment was in the best location across from the Olivia Balmes Hotel with 15-20 min walking distance to popular neighborhoods like La Rambla, Gothic Quarter, Gracia neighborhoods. It fit all 5 people in our party comfortably and the rooms had a beautiful presentation when we walked in and seamless checkin/checkout process. Overall the experience was good, and loved that there were 2 full bathrooms for our guests to use plus tons of closet/storage space in each room. Also really liked the lighting in the apartment and overall amenities.
Note that the building's elevator is very tiny (common in Europe, but just note this if you have a lot of big luggage). We had some issues with the master shower not working on the first night, but we were able to report it and get the shower fixed by Sito's team promptly the next day. They spoke English which was very helpful. One thing to note that there is major construction and loud banging/drilling above the apt every weekday morning around 8 am, so that disrupted our sleep on 2 of our days we stayed (no construction on the weekends). And, the dishwasher had a weird smell (didn't bother me personally, but some of our guests were sensitive to it), which still persisted throughout the 5 days we were there. We also ended up running out of toilet paper between the 5 of us halfway through our stay, so in the future I'd recommend stocking up on this for guests. Other than these minor issues, I'd recommend this location for future guests to stay.
