Hotel Aire de Bardenas is located in the northern area of Spain, in the middle of a fairly rural area in the Bardenas Reales Nature Reserve. It's known for its minimalistic architecture and views into the open fields and it's basically an assembly of sleek boxes in the landscape. Two architects from Barcelona, Emiliano Lopez and Mónica Rivera, own the four star hotel with 22 rooms, some of which include an outside bathtub. The food is apparently fairly delicious and the hotel grows its own vegetables.
Head over to the hotel's website and hit "Me gusta", it's a great concept and seriously well exectuted.
On a side note, I apologize for the slower pace of updates. I was gone for a while because of a small medical issue but I should be back to more or less full speed now. As usual, thanks for reading!
