Good location to the main square & great to have a bit of free wireless internet - although this cant be accessed from the rooms.
Hot showers were a bit hit and miss. Beds a bit old, lumpy and saggy.
Breakfast very average. If you get laundry done - make sure you ask to weigh it before sending out.
Good base to do Inca Trail from.

This is a basic hostal, so be prepared for dorm-room set up (even if not dorming) and lukewarm low pressure water. Breakfasts are also average, so go to Jack's cafe for nourishment. Depending on room, you may be able to hear noise from the street / the night clubs.

But the location is amazing - short stroll to Plaza de Armas and skip to restaurants/clubs.

We had a wonderful stay at San Isidro Labrador. Estela was very nice, speaks perfect english, and had our room and reservation ready. Rooms are clean, area is perfect, very safe, very friendly. We paid US$40 for our matrimonial room, which is OK in cusco - there are much less expensive hotels, but we wanted to be safe and comfortable. Only negative - skylights and windows mean you wake when the sun rises - which was around 5:30 on October 3rd.

The San Isidro Labrador is a nice hotel. It has an open area in the middle with a lovely staircase, and rooms upstairs and downstairs. When we arrived they brought our bags upstairs - doesn't sound like a big deal, I know, but when you're slightly winded from the altitude it is much appreciated! They made us a fresh cup of coca tea right away which also helped. Rooms are rustic and basic but nice. Ours had 3 single beds. There is no TV, which isn't too big of a deal if you don't plan on staying inside, but as you are getting used to the altitude it might be nice as a distraction. Not a big deal, though. The space heater kept the room at a comfortable temperature, and you could always ask for extra blankets. Overall, a nice place. If you're looking for luxury, don't stay here, but for a comfortable and pleasant stay it is a good deal. Location is stellar, with the town square right down the street. And for those who are concerned, we were told that the hotel keeps oxygen at the front desk. Luckily we didn't need it!! Breakfast is simple, bread and jam and coca tea. We only woke early enough for breakfast the day we went to Machu Picchu anyway!
