It was the first time using Airbnb and didn't know what to expect. My friends got there before me so they handled the check in with Fernando. They told me it was all very easy and that Fernando was super nice and friendly. I actually never met Fernando, he had a meeting when we were supposed to meet, but the check out was really smooth anyway and Fernando seemed very nice. I had daily contact with him, he came with suggestions on places to see and restaurants to visit. He also responded very quick and were helpful.
The location of the apartment was perfect. It's on a quiet street just right next to Gran Via and also like 50-100 meters to Santo Domingo subway station. Took us roughly 30mins from the airport. The apartment is in a walkable distance from most sights, depending on your preference of course, but definately walkable to Puerta del sol and Plaza Mayor.
The apartment itself was clean, fresh and well equipped.
All in all, we had a great stay. The most difficult part about our stay was the length of the wi-fi password, which pretty much says it all.
Gracias Fernando!
