Great location in Anton Martin - it’s still in the “Old” hemisphere of the city but much quieter than Malasaña.
Lots of stairs - potentially an issue for the elderly / anyone with a permanent or temporary disability. The flat is however very pretty, very light. The AC works very well, which is an absolute must in Madrid as summer temperatures can climb towards 40c.
I was a little anxious about the noise restrictions because Madrid is definitely a night time city and most people haven’t even sat down for dinner at 10pm let alone gone silent for the night, but i tried my best to not make too much noise coming in after dark and no one complained so I guess the listing is more a warning against parties / loud music at night etc….
5/5
Would stay again
