I stayed at Javier’s place for two months. I’ll go through pros and cons for those considering booking!
The pros: 1) Amazing location in a vibrant neighborhood with amenities close. 2) Beautiful layout with gorgeous light through windows. 3) Working elevator. 4) Relatively clean. 5) Host generally let’s you do your thing unbothered. 6) Javier was kind enough to let me reschedule my reservation when I was delayed by a medical problem.
The cons: 1) Javier means well and eventually gets back to you, but as others note he is slow to respond or only responds to urgent things or multiple nudges. 2) Very little hot water (four to five minutes max; I used a bucket and turned off water except for rinsing to have enough for one shower). 3) Not as stylish or aesthetically pleasing as photos show (if design is your thing) due to wear and tear—couch is weathered and stained now, floor slightly different, no rugs, no plants, etc. which detracted from style of place. I bought my own plants to make it feel homier. 4) Given the wear and tear on apartment, price didn’t match value for a long term monthly rate in that neighborhood.
Despite all I’ve described above, I would stay here again for a long-term visit to Madrid. The place grew on me and I loved the area.
