Marta’s apartment is stunning, even better than the photos show it to be. It is elegant, stylish and spacious. We loved staying in the centre of the old town. It has so much atmosphere and is close to everything. Even with such glowing praise of the apartment, the best thing about it is Marta herself. She is the best host we have ever had. Nothing is too much trouble- she is warm and friendly, easily contactable and a wealth of knowledge.
I doubt that you can find a better place to stay in Bilbao.
