The location of the apartment was fantastic, very close to attractions like Mercado de San Miguel and the Plaza Mayor.
Check in was seamless. The apartment was spotless and had high quality finishes. The beds were comfortable as well. The posting says that three beds are available, though they usually only keep two in the apartment. If you need the third bed, be sure to specify that in your request.
The only issue was with hot water. One night the shower only briefly had hot water, but the next night the issue had disappeared.
