Diego's place is a must stay when visiting Bilbao. It is a few minutes walk to Old Town, where there are many cafes/restaurants/bars/shops.....you name it, it is there! There is a lovely park just a stone's throw from the apartment with fantastic views of Bilbao, nestled in the hills. If you are feeling up for it, the 200 stairs down to the Plaza Nueva provide easy access and a great workout on the way back up.
The apartment itself is very nice. It is spacious, nicely decorated, and quite comfortable, not to mention quiet. It was lovely to come back to a peaceful environment after busy days of meetings and exploring the city.
Diego is the best host I've had in all of my years of Airbnb's. He was extremely communicative and accessible, and when I had unexpected personal issues after leaving his place he was extremely helpful and caring. He has gone above and beyond the expectations of a host and I am very grateful.
I highly recommend Diego's place and would stay here again anytime I'm in Bilbao. I hope to return soon!
