We were a group of 3 which spent 4 nights @ Samuel & Slavko amazing flat in Sants-Montjuïc.
The apartment is specious and very tastefully renovated. We did not really know what to expect as this was our first experience with airbnb, so it was defienetly was a great surprise.
Both Samuel & Slavko were great hosts, giving us whatever space we wanted alongside sharing some key interest points in Barcelona.
We will most defiantly recommend all our friends to stay there and you should try them as well.
