This was a nice find.
Apartment is located right on the southern tip of Amsterdam Circle, which not only means you have great parks, cafes and restaurants within walking distance (i.e. a couple of minutes), but also peace and quiet since you're shielded off from busy main roads.
Located on the 3rd floor, the space itself is beautiful, tastefully decorated, and comfortable. Plenty of afternoon sun as well if you feel like hanging out on the balcony.
Beds are fantastically comfortable, and hot water in the shower works well. Only issue was internet was a bit dicey on the last day of our stay (Mao's going to look into it, might have been a temporary issue with the ISP).
Overall a great stay, Mao and Brenda are wonderful hosts :)
