My husband and I stay at Giardino almost every time we go to Playa Guiones in the Nosara area. Marcel and Myriam are the consummate hosts. Myriam is great at finding entertainment in the area for you.
Every morning, a simple but filling breakfast is served to order near the pool. Great time to reflect about the rest of the day. Marcel and/or Myriam are often sitting at an adjoining table, and are happy to talk about your vacation plans or anything else that comes up! Between them, they speak Spanish, English and German, providing ease of communication for a variety of guests.
The lush grounds are ideal for languidly viewing as you lie in a hammock, nodding off. :-)
Having stayed in each type of room, I recommend one of the Deluxe rooms or the apartment. The Standard rooms are smaller and not as light as the others, so after our first visit we upgraded.
Some of the Deluxe rooms we've stayed in have delightful paintings directly painted on the wall, and they all have a kitchen-like section of the room where you can make coffee, store items in a refrigerator and have a sink for a quick clean-up.
The apartment is a good option for when you want to stretch out and have a small but serviceable kitchen (and table and chairs!) at your fingertips. We have relatives in town so we appreciate the room when everyone comes over for an afternoon or evening.
The only gentle criticism I can offer is that the pillows could be replaced in some of the rooms. I bring one with me no matter where I go, so it's not a deal breaker. I've stayed in other, higher end hotels in the area and so far I can't say any of them have fantastic pillows. :-\
I'm told the menu at the restaurant is very good, but can't attest to it anymore. My husband and I used to love going there for the wood grilled pizza and wonderful pulpo (octopus) salad, but since we both found out we can't have gluten there isn't much on the menu that we're able to have. :-( Hoping for more gluten free options in the future. The restaurant has a full bar, so it's still great for a pre-dinner drink for us.
All in all, Giardino is a fun and friendly base to have while you're in Playa Guiones!
