First the plus:
-perfect location, 100m from underground Metro/Railway station
-nice entrance hall and elevator
-quiet and clean, towels provided
-good price, friendly owner
the minus:
-the common kitchen has very worn furniture and is not nice
-the bathroom furniture is close to falling apart
-the room has one single power plug only, a huge TV is there but no power for it.
-the pictures do not show the bad condition of the flat.
Summary:
We were only there for sleeping and a shower in the morning or evening.
If You only need this, there is hardly a better location to find.
Go down to the river by public elevator in the park, go up to the hill by funicular train,
go anywhere by Euskotren or Metro, all within 100m. Breakfast bar around the corner,
pub with snacks 200m. Oldtown 15min walk, newtown and Guggenheim the same.
