I had a very nice stay at the Blue Lagoon this past weekend, and can confidently give it a 4/5 stars. The house’s location, accommodations, comfort, and amenities it comes with are all excellent and I would highly recommend. What lowered this from a 5 star review was a few surprises that we were not informed of until after arrival.
Even with paying the additional fee for heating fee for the pool and hot tub, both required significant warm up time before they were useable. I would expect to require at least 30 minutes before it gets to full temperature, and this can not be done remotely before you return home. During our stay the jets were not working for the spa, though our host did send someone out to fix it while we were there. I would have expected when charging a significant surcharge the host would have ensured it was properly functioning.
We were also informed on arrival that the dryer in the main house was malfunctioning, though the studio had its own so it was not a big deal. If you are only booking one unit I would check whether this is functioning and plan accordingly.
The host was very responsive when communicating with us and was helpful in resolving any issues we had before and during booking. If I was booking in San Diego again I would consider this location and overall it was a very positive experience.
