We had a wonderful stay at Begoña's place. It's well situated in a lively but calm during the night district. Sightseeings such as Guggenheim museum are very close. Even the bus that goes to the airport is also just a couple of blocks away. There's plenty of bars and grocery stores around, the metro stop to take you to the ocean is also a few minutes away.
The bathroom is private and very clean, the room itself as well. Would definitely recommend!
