Everything you expect from a youth hostel. Not sparkling but comfortable. Ok rooms, friendly staff, nice kitchen area and nice roof terrace.

I arrived late to Lima and was leaving early so I just needed a place to sleep for 6 hours and shower. The hostel was kind of tatty but it was cheap and the guy in reception was lovely even though I arrived at 1am. However, the bathroom didn't have a light bulb so I couldn't shower until the morning when I saw that the bathroom also wasn't clean. My door didn't lock which didn't make me feel too safe at night and would have been a real problem if I'd wanted to leave my room. Plus the you can here everything from reception and the next door rooms, so it's not a place for a quiet night.
So no big problem until when I them for the hotel booking site I used the management from k'usillu's wrote me a series of abusive emails. They used some really offensive language and kept sending them until I had to block them from my e-mail. The hotel was just not very good but the managements abusive email were terrible.

We were in Lima just for a night befor ecatching an early flight out to Juliaca. We just needed a place we would crash and get a good sleep in a good area. Area is fantastic, right on a main strip and close to the ocean and Larcomar shopping centre. Maybe it was just our room, however the noise coming in from outside was overwhelming at night, and on the other side of us was the lounge where the nightstaff was watching movies (not quietly) all night. Needless to say, there was no sleep, and no hot water. I've read the breakfwas was good, unfortunately we had to leave for our flight prior to it starting.

i must admit i was a bit disappointed at first with the kusillu's hostel.for one,i'd say that it doesn't look anything like the pictures on their website.i was expecting a brand new place but in fact,it looks a bit tired,especially the reception area. my biggest beef was with the rooms ( i stayed in a single & a double ) which are basically windowless so they have very little light and can also be quite stuffy.( they advertise a ' double with terrace ' but there's no such thing as a terrace,it's just an extra room on the side )
on the other end,there were many positives to the place , starting with its location , smack in the middle of miraflores with all the conveniences at your door step.the hostel is very clean,they even came and clean my room daily which i didn't expect ! ( jaime is the hardest working man i have ever seen ! ) , breakfast is included in the price - fresh coffee and rolls , you have full use of the kitchen if you so desire.the staff was super friendly and always willing to help though only ricardo speaks perfect english.
i would say that all in all,the place grew on me , the positives overrode the negatives, i would recommend it if you are not too fussy but looking for a clean , safe place to stay in lima that won't cost you an arm & a leg.
also , note that they are expending and building new rooms upstairs,hopefully with windows !!
