The good: the location in Chamberi is fantastic. It's far enough away from the center to feel more like a local but still well connected. It's right by Plaza de Olavide, and a short walk from C. Ponzano with tons of restaurants, bars, and markets in between so you can skip the crowds of tourists altogether if you want. Check in was easy, communication with hosts was quick, and the apartment was clean. The terrace was spectacular.
The less than great: The space is adequate but pretty basic. While it had amenities like a coffee pot and washer it lacked most basics like coffee, filters, soap, etc. There are markets nearby but it would be nice not to have to shop for things that are often included in rentals.
