Let's start with the good: Great location, 1 block away from stairs that go directly to the beach, close to Oceanside Train station, walking distance from Oceanside pier and several places to eat.
What's not so good? I guess the infrastructure needs a little bit of tender and love. Most of the things seems to be very outdated and that might not feel good for several people (for instance: For me wasn't an issue, but for my wife it was).
There's no AC in the unit and during the summer days the place can get way too hot... specially on the second floor. The place offers a lot of fans that could help mitigate a bit the issue, but it's still a thing to consider, specially at night (BTW: several of the fans are very dirty and/or have pieces broken so they won't work 100% well)
About the cleanliness: Several utensils from the kitchen were not clean and we had to wash them ourselves before even try to use them, the rug on the family room is very dirty and while I was looking for some toys that fell under the sofa I felt a bit scared to put my hand in there after I saw underneath.
The cherry on top of the cake: After 5 out of our 8 days in our stay, my 6 y/o daughter and myself started to get a weird rash on our bodies... At first wife and myself thought this might be chickenpox (wild guess because everyone is fully vaccinated) or some other form of virus, so we left the place before the checkout date was done. After further review by our family doctor and pediatrician for my daughter's case that hypothesis was discarded and both suggested it might either be some sort of poison ivy rash or bed bugs.
Given that my 6 y/o daughter shared the same bed with myself and neither my wife or my other kid got that ugly rash, I would like to leave the conclusions up to the reader.
Would I visit this place again? No.
Would I recommend it? Probably not.. I would just mention its location, but with a huge warning on what you should expect.
