Overall I would recommend Javier's location. It is centrally located near Sol metro stop (5 minutes) and within walking distance of plenty of restaurants, bars and tourist attractions.
Pro:
- Great location, near Sol Metro. Centrally located between Royal Palace of Madrid and El Retiro Park. Plenty of bars, shopping and restaurants.
- Good accommodations. Comfortable beds, clean sheets, stocked kitchen with cups plates and utensils.
- Complete with clothes washing machine.
- Working AC in the main living room and master bedroom. Fan in the guest room.
- Two nice small balcony.
Cons:
- Located above a popular street with bars. Noise can continue well into the early morning. Windows well insulated against noise in the living rooms, less so in the bedrooms. However, noise is an expectable levels. (I'm use to living in a busy city.)
- A little worn. The apartment is well loved by travelers, as the popularity and reviews reflect.
- Key location at a separate location. It's near by however little bit of an extra step. We checked in out, so this was avoided. Someone met us at the airbnb.
