We arrived at K'usillu's after 11pm right from the airport and would be leaving the next morning before 8am to go right back to the airport. Upon arrival we were greeted by an extremely friendly staff person. Despite knowing how brief our stay would be, he made sure to run down all the amenities of the hostel, breakfast time, accessible kitchen, common areas, wifi connection info, etc. Additionally he provided us with a map of Miraflores, and wrote detailed notes on it about where the hostel was located in relation to major sites or attractions.
The hostel is just a few blocks from Parque Kennedy, the center of Miraflores, featuring numerous restaurants, cafes, and artisan markets all within short walking distance.
Our room itself was nice, no thrills, hostel room. The bathroom however featured one of the best showers we had in Peru, and one of the best showers I've had anywhere. Definitely a pleasant surprise after spending several hot sweaty days in the Iquitos jungle and then being on an airplane.
My only minor complaint was that our room was a little close to one of the common areas, so when some other travellers came back to the hostel from what I assume was a night of drinking, they hung out for awhile in the common room, and it was a little loud in our room.
