Natalia's studio- apartment was great. I stayed for three weeks (and worked from the apartment) and it was a great place to work from, but also to visit the 'old city'. The apartment is incredibly functional and very well-designed; and it was comfortable. You can go to Mercado de Rojas Clemente to get your fresh fruits, vegetables and whatever else you need. Only disadvantage for someone staying long term was that there was no access to 'regular' TV (though there is access to Netflix, etc, which is what most people care about!). Would come back.
