We stayed at the Peace Lodge for 1 night and it was absolutely beautiful and fantastic. We paid about $400 for a deluxe room and it is beautiful. The room had two Jaccuzi’s – One on the patio overlooking the gardens and the rain forest and the other in the bathroom. The bathroom was beautiful with a waterfall, rain shower, water fall shower (separate from the waterfall). There are two levels and our room was on the higher level (may be all deluxe rooms are). I would highly recommend getting the rooms on the higher level as the patio is above the tree (plants) immediately in front of the building giving a wonderful view of the mountains.
We had lunch at the restaurant by the lake and swimming pool, which was very nice. The dinner at the main restaurant was fairly decent as well. They offer body massages in the rooms only and it was very nice and good value for money. The resort has a netted area where you can see birds, similar one for butterflies, one for frogs, snaketarium, humming bird park etc. La Paz waterfalls (five waterfalls) are a within the complex and absolutely beautiful. Overall, this was one of the best resorts we stayed in Costa Rica and although expensive, it was value for money.
General tips: We were in Costa Rica for a week and rented a car. If you rent a car, do get GPS as signs are rare and far in-between. The GPS was a life saver. Roads were not terrible as I expected although I would not compare it to any thing in the US or Europe. People seemed friendly and we did not feel scared or threatened at any time and we drove to every where (local restaurant in La Fortuna and in San Jose). I would not recommend driving in San Jose down town area unless you have already driven in other developing countries with aggressive driving. If you are renting with Europcar, be aware that they do not have a counter at the airport (most other car rental companies do) and you have to call they to be picked up or take a cab. It was very frustrating as we called and were told 10 minutes. We called every 10 minutes and were told the same thing with no shuttle 90 minutes later when we took a cab. The office was very disorganized. The car was nice and return was easy. Most car agencies have similar cars so go with any reputed rental agency.
