Can we leave bags at this hotel while we go to Machu Picchu for a night?
Regarding the luggage, of course you can leave free, until your return.
Yes, we left our luggage there during our absence and at our request they brought them to our new room when we got back before we arrived (we arrived back close to midnight).
Yes the front desk has an area behind them that will allow to store your luggage. I would get down their a bit early if you have a lot of bags as the space was limited but I am sure they will facilitate other means for you if that happened as they are very accommodating. Hope this helps!
