Great little centrally located apartment about 15-20 min walk from almost anywhere you’d like to go. Comfortable beds and good for sleeping as it’s dark at night because it’s an interior apt. Lots of little grocery stores near by and many great restaurants too. This is a typical Spanish apartment so you will hear the neighbours in the halls but everyone we met was pleasant.
If markets are your thing (and they should be in Madrid) you are about 15 min walk to the touristy but awesome San Miguel market, and about 5 min from the less touristy Anton Martin market. The San Fernando market is mostly full of locals and inexpensive and excellent for ah hour or so. Gets very busy.
