Centrally located and quiet. On a side street off busy Gran Vía. Easy to walk to, or use public transport to many locations. The apartment is fairly clean, but there were grease stains on cupboards and food stains on the table. The bed is comfortable with exterior shutters on the windows that block nearly all light. The shower is a good size, but the second person taking a shower will need to wait for the water to heat up. The bathroom sink is ridiculously small. You can wash your hands in it, but anything else involves water all over the floor. Bathroom in general is pokey. Wi-Fi excellent, with 300 MB/s+ speeds. Madrid Rentals appear to own the whole building which has about 16 apartments over 4 floors. The common areas, especially the elevator/lift are not in great shape. You use an app to enter the building and open the apartment door. This is cumbersome, involving finding the app on your phone, opening it, selecting the door to open etc. A simple keycode for the main door would have been much easier as would a key or code for the apartment. I also found it a bit strange that you communicate with "Madrid Rentals" all the time. Their communication is never signed, e.g., Alejandro etc. Almost as if they want to stay anonymous to avoid responsibility. Overall, I would look for different accommodation next time, but would stay here again in a pinch.
