I reserved a double room through email and got a notification that our double bed room was reserved. When we arrived to Samay Wasi 1, it turned out that they didn´t have a double bed room for us because they had already given it to somebody else, strangely. We decided not to make a fuss and took a twin room. We asked the first night for a reservation for another two, which was no problem at all according to the guy at reception.
The next morning my girlfriend fell ill and we had to go the clinic, which the hostel arranged for us so they knew very well where we were and why. When we came back from the clinic a couple of hours later (still under the impression that we had the room for another two days) we were asked to check out... I got a bit irritated because that morning a had asked the reception if we could change rooms to a double bed room, which was no problem. The girl from reception took it very seriously though (mainly because she noticed my girlfriend was sick) and arranged that we could stay. So in the end it turned out quite alright, but also it was a very unnecessary hastle. It really didn´t seem like they knew what there were doing with their administration.
Also, our room (3) wasn´t very clean. I have mild dust allergy and immediately after entering the room I noticed my eyes tearing up and my nose started to run. The bed was okay but the pillow was absolutely terrible. I threw it out of the bed after 4 seconds and used a sweater for a pillow. The room was very cold at night due to inadequate isolation. Worst of all, it´s very, very noisy! You can literary hear everything the people in the room above you say and do.
The staff are very nice and friendly but most of them don´t speak very well English so there is always a language barrier. The breakfast is included, which makes for an overall good value for this hostel, but was plain (just breadrolls and marmelade). You can add extra options for breakfast which is nice but it´ll cost you some extra soles.
We left our baggage here during the Inca Trail, without problems. When we came back from the hike, we moved to Samay Wasi 2 (the star room) which was way better!
I wouldn´t easily recommend this hostel, due to our negative experience the first day.
