lovely host and even let us have a late check out as an apology for works going on in the communal areas of the building which wasn't a problem to us anyway.
Nice facilities and some nice touches with some of the kitchen equipment they provided, means we didn't have to bring boring things like washing up liquid!
it's on the ground floor and overlooks a small yard which means very little natural light gets in, but that means it's always nice and cool in a hot city. and there is air conditioning too.
the location is great for lots of plazas, the retiro park, the railway and bus station, and the Reina Sofia museum. The park was lovely especially the boating lake which was very cheap for a long hire of a rowing boat.
we'd definitely use the apartment again if we return to Madrid.
