The apartment was lovely and cosy with all the home comforts. The location is great, it felt like being in amongst locals rather than tourist traps. The Mercado de San Fernando is right up the road and absolutely worth a visit (when the shops aren't closed for the afternoon). Only thing to note is that the building key is a bit stiff, it does work but takes a bit of jiggling! There is also no lift and it is a third floor apartment, though this was not a problem for us as we didn't have too much luggage. Highly recommend staying here if you want to visit Madrid like a local!
