That's a great place to visit San Diego from. It's a separate apartment below the main house, with an independent kitchen, bathroom, living room and two bedrooms. It's a nice place, albeit a bit small.
Pros:
- The place is very clean
- There's indeed a huge TV and a comfy sofa
- There's ton of equipment (kitchen ware, salt, oil, etc…), and the place is well furnished
- There's a small garden you can enjoy
- It's very well located, and the neighborhood is great
- You can park a car right by the house
Cons:
- The place is actually super tiny, smaller than it looks in the pictures. It can fit four people, but you won't have much personal space.
- There's only one window in the living room. It's quite large, but light quite doesn't get inside the place, especially in the evening.
- As other guests have reported, you'll indeed hear some water sounds. Wether it bothers you is up to you. It didn't bother me personally since it's a white noise, but it did wake up the kids at some point.
