Overall a lovely little apartment right on the Carrera del Darro in a typical old building with several similar apartments all backing onto a central atrium - the atrium door opens right onto the Carrera del Darro, and in a few paces you're looking up at the Alhambra from a lovely public space with several reasonably-priced restaurants, a guitarist or 2 playing Spanish music, etc.
The Albaicin is right behind, with lovely little streets and more bars/restaurants, & within a short (steep) walk you reach Mirador de San Nicolas with a fantastic view of the Alhambra from across the valley.
The apartment's well-appointed including a washing machine. It is small, but with the sofa bed it could fairly easily sleep 6 people (but could feel a bit of a squeeze). The kitchen is very small but perfectly functional and adequate.
The only real problem we had was with the street noise outside, especially at night - Carrera del Darro (cobbled street) has taxis, buses, delivery vehicles & mopeds going past at regular intervals all night & so we found it impossible to sleep in the lower double bedroom. We resorted to one of us sleeping on the sofa bed in the living area, the other buying earplugs from the local supermarket. It's a ground floor apartment and some windows back directly onto a side street.
Overall we enjoyed our stay here but we'd urge the owners to address the noise issues somehow.
