If you are staying here as part of a tour group, or for one night only, it's probably fine. The rooms are clean, comfortable and warm. There are plenty of blankets on the bed, and a little heater is provided. There is a TV - but hardly any English channels. WiFi is available in the reception, and works well there. Breakfast is inconsistent, but OK. Eggs are always given, sometimes yogurt, sometimes cheese. It's possible to have breakfast a little early - officially it's from 06.00 - 09.00. Tour groups seemed to have no problem eating before 06.00. The staff are friendly and do their best.
The main problem with the Posada del Colca is that it's impossible to sleep after 04.30. This is OK if you're getting up early to go to the Cruz del Condor. We had a room facing on to what is supposedly a pedestrian street, but cars, pick-up trucks and vans would line up outside the front door waiting to collect guests. The noise was awful - radios blaring, voices, doors slamming, and engines revving.
On the first morning - when we got up at 05.00, the shower was hot. The following two mornings it was not. The second day it was tepid, the third, cold. To be fair, the staff did boil water for us and carry it up to our room, but the hotel simply does not have the capacity to serve the number of mainly large groups that it caters for.
One day of our stay the room was not serviced. When I asked why I was told they thought we were checking out - even though it was way past check out time, and we'd paid for our whole stay on arrival, and told reception staff twice, that we were staying for three nights.
The manager apologised profusely when I mentioned all these problems, but did not offer any recompense - just said that he hoped we would stay again if we were in the area. Sadly, I can only say that the Posada del Colca is not good value for money (PEN 129 per night for a double) and I could not recommend it to anyone.
