Very large apartment in a great location. Subway is just outside the front door. Easy walk to Gothic quarter and Sagrada Familia. Apartment has 3 bedrooms plus a separate workspace.
Some minor negatives - super tiny shower, very minimal supplies provided (toilet paper, salt/pepper, paper towels etc), some maintenance is needed to replace lightbulbs, fix a dining chair and replace/fix microwave.
All in all a good option for a family to spread out while enjoying the sights of Barcelona.
