"San Pasucal" is a beautiful custom designed log cabin, built from pine. It's a very unique structure and absolutely gorgeous throughout, with big windows that let in lots of light and allow you to see the beautiful landscape all around. There is a pool table, bar, seating area, and even a drum set and DJ studio (if you're a musician, you might be invited to jam with the hosts).
Speaking of music, the hosts are very serious DJs and producers. If you like electronic music, this is the place for you! The house isn't bumping like a party and the hosts always asked me if it was OK before making noise (of course it was OK, I'm a hobbyist DJ myself). If you play, bring your tracks and Serato along--you'll have a place to stay in practice.
There is enough room for a very large group - the house can sleep 16. When I stayed, there were only a few people. So, depending on the crowd who is there, it can be either a peaceful or lively atmosphere and this can change from day to day. You're staying in a house with public spaces, and if people are there with kids, they're going to be kids. Accordingly, don't go into this place with any fixed set of expectations (other than a clean comfortable room, friendly host, reasonable price and beautiful location). This is NOT a five star resort--it's a very nice, well kept and huge farm house in the Costa Rican countryside, with a wide variety of visitors, and is the kind of place that very few visitors to Costa Rica ever experience.
In my mind, the location is close to perfect - about a 10 minute drive to the city of Quesada, but off the beaten path. It's quiet and peaceful. You're close to the city but not in it. A river runs through the property, which is a short walk (and you can pet the horse). There is a cat and two large, friendly dogs, like you'll find at most farms. A waterfall is a short drive away. It's relatively close to La Fortuna and Arenal as well, but well away from the tourist bedlam.
Internet service is reliable and works well. It's not especially fast, but no Internet service in Costa Rica is fast. It was fast enough for Web browsing, email, and (SENSITIVE CONTENTS HIDDEN), but isn't fast enough for large file transfers. Again, go into this with the right set of expectations--you're on a farm in rural Costa Rica, not central Shinjuku, Tokyo.
The hostess is very friendly. She speaks perfect English, and can help with any arrangements you may need.
