This was our first time going to San Carlos and we were a little intimated. John was super helpful on guiding us on how to get there and what to expect; he gave some excellent recommendations on what we should do out there.
The condo was excellent. The kitchen had everything we needed to make meals. The beds we all very comfortable and the A/C worked perfectly. There was a TV with cable, though we didn't watch it much. The added bonus was the free wifi, the USA telephone and the local telephone. It made it really easy to get a hold of people and even get some work done!
The resort itself feels very safe. There is always staff walking around and checking on people and things. The entrance is actually guarded which adds to feeling very safe. The front desk was always helpful and was able to give us directions to any place we needed to find (although using the free wifi allowed us to search things up on Google!). They even had ice and purified water that you can buy!
I highly recommend renting kayaks and rowing out to the island that you can see from the room. It definitely was a work out, but it was well worth it. The island is really cool and you can search through little caves and tide pools. We ended up making it to the island right around sunset which was incredibly beautiful. Just keep in mind, that the beach to get onto the island is on the opposite side.
