Marina's apartment is very nice with a perfect location as it is only 1-2 minutes walk from Bilbao metro station. It is also walking distance to Gran Via (it is around 1.2 km away and is 15 minutes walk). We enjoyed the walk to Gran Via as there are plenty of shops and restaurants around.

The apartment itself is stylish, clean and very organized. It has all the amenities that you would be needing for your stay. The only thing we noticed is that the walls are a bit thin (we can hear the utensils from other units). But over-all, we liked the apartment.

Marina is also very helpful and she provided us with brochures & maps and she is very knowledgeable about the attractions in Madrid. She can give you all the information that you'll be needing for your visit in the city. She will even provide you ideas and information on Madrid's sights through email prior to your visit.
