This place is exactly as advertised - we stayed for a week and it was great! It is located under a flight path, and planes do go really low, but the noise when inside isn’t all that bad. We got used to it after a couple of days - to the point where we didn’t notice that they were flying over us. They provided complimentary earbuds in case you need them, but we never had to use them.
A couple of things to note: there was an overwhelming smell coming from the room when we first arrived, but it just may have been old wood or mold from the house itself. The shower faucet only half worked; when turning on the shower, half of the water came out of the shower faucet and the other half out of the tub faucet.
Otherwise, the stay here is fantastic and we would 100% stay here again. The views from the balcony are incredible to just kick back and relax The location is wonderful - there are scooters everywhere, so we spent a good amount of time scootering to the downtown area or Balboa Park. The beaches are anywhere from a 15-30 min Uber/Lyft ride. And lastly, Greg, the on-site manager was amazing! If there was anything we needed, Greg helped make it happen and did so in such a timely manner. You won’t be disappointed in your stay here.
