This place is great for several reasons: Firstly the staff at Clickandflat are great, very welcoming and friendly. Alex helped us with everything we needed and was friendly, helpful and professional.
The flat itself is gorgeous, lovely lay out and a pleasure to stay at. Lovely high ceilings, modern and sophisticated furniture, fixtures and styling. Everything worked! (Can't say that for other places we stayed) and the quality of all the appliances are very good.
The location is great too, we found several great restaurants and bars very close by with both locals and visitors. Not just your typical 'Ramblas' hordes, but interesting and diverse people and experiences.
I recommend this place and would give more than 5-stars if I could.
