Loved our stay at Stacey's Dragonfly cottage.
It is minutes away from Balboa Park and all that the park has to offer. It's also close to Hillcrest, just a few minutes walk to shops, cafes and restaurants. Getting downtown was also easy.
Stacey was great with recommendations and general 'neighbourliness'.
The only negative was that the air con was a bit loud (but we didn't need it after the first night so not an issue for us) Parking was also an issue at weekends, so be prepared to do a bit of Parking hunting!
Overall we loved it and would definitely go back.
