We stayed here in May for 5 nights in Lima for a wedding. I agree with other posters that it's not a 5 star hotel, but it's definitely at least a solid 3+. I'd stay there again if I was staying in San Isidro, but next time I return to Lima I'll probably try to stay in Miraflores instead closer to the ocean.
We never had any problems retrieving our key at the front desk, in fact the desk staff and the doormen were extremely welcoming and helpful every time we went in or out. The breakfast was pretty good, room service was just ok (typical for hotel food), and I appreciated the amenities such as the extremely comfortable bed, safe, alarm clock, and bath supplies that we definitely didn't get at the hotels we stayed in after leaving Lima for Cusco and Aguas Calientes. The decor is very comtemporary and stylish. There was work going on at the hotel but we didn't get woken up by renovation noise (just by the birds who called to each other right outside our window at dawn every day).
The hotel gets a lot of people who fly to Cusco and MP before returning to LIma for another night and they are very good about storing bags, we had 5 friends who stored luggage and nobody had any issues.
The business center has a printer and 3 computers with internet access, but they weren't always working every day. The location near the Wong grocery store, Starbucks and a bunch of other restaurants on the gringo cirlce was a definite benefit for picking up food and drinks when we just wanted something quick, but mostly we ate out with friends in Miraflores. Of the restaurants whose names I can remember...Las Brujas de Cachices (sp?) had excellent typical Peruvian food, I was very sad we didn't get back to LeMar to eat after having cocktails there, and the restaurants at Lorcomar plaza can't be beat for the view (food was good but not spectacular).
The one issue we had was that a lot of taxi drivers didn't seem to recognize the hotel by name. It seems it changed names recently, so make sure you take a card from the front desk with the address with you when you go out.
