I spent 6 nights here and used Hotel La Rosa de America as my "home base" for day trips with the rental car. Most of the other guests tend to stay only one or two nights before they leave or start their journey in Costa Rica. The room was clean and the mattress was comfortable. I have always slept very well. For its proximity to the airport it is really quiet. The Superior rooms are equipped with air conditioning and a fan.
I especially liked the large, well-kept garden with various trees and plants. The pool was also clean and I used it almost every day to cool down after a hot and humid day. Breakfast is served from 7 clock, but you can order a "breakfast to go" if you need or want to leave earlier. As far as I've seen, there are a few restaurants within walking distance and there's also a restaurant in the hotel, where you can have dinner. But I can't say anything about that, as I've always eaten somewhere else before driving back to the hotel. At night, the parking area and the hotel are closed by a gate.
The staff was friendly, cheerful and very helpful. For example, before my arrival they helped me obtain several rental car quotes and the chosen car was delivered directly to the hotel at no extra charge.
At Hotel La Rosa de America the value-for-money ratio is right, and should I return to Costa Rica, I would not hesitate to stay here again.
