Gemma and Alex's home was as described in the listing, sparkling clean and modern design, and a very convenient location near Park Guell and metro spots within a 15-minute walk.
We were unfortunately not able to meet Gemma or Alex in person, however they had a friend meet us to show us the apartment upon our arrival. Check-in was smooth and easy, and we were provided with maps of where the apartment is located in relation to nearby sights and metro stops. (Metro cards were easy to buy and metro easy to navigate.)
We had a very early flight departing on our last day, and Alex was so kind and gracious to reserve a taxi for us for 4am on our departure day. That was a huge relief to us, especially as our Spanish is very limited and we were concerned about finding a taxi at that early morning hour in a safe manner.
The beds were comfy, linens and towels clean, and the space overall was very very clean. I spotted some ants one day in the spice cabinet, and we let them know and it was taken care of. The Wifi access was great and no issues with connectivity, which I've occasionally encountered at other Airbnb homes. We frequented a nearby bakery (365, which I think may be a regional chain?) often and they had delicious pastries and were gracious for our family's limited Spanish-speaking skills. ;)
I would absolutely recommend Gemma and Alex's home for visitors to Barcelona!
