This location cannot be beat! It was quiet, clean and lovely. The house is small, but bright and sunny and had what we needed. We brought our older pup and 2 kiddos along and everyone was comfortable and happy. The highlight is the location- on a quiet street, right above the lagoon, a 5 minute, easy walk to the beach. As another renter noted, the beaches close-by are not dog friendly, so be aware of that.
We enjoyed Carlsbad- there was a great pizza place we went to twice (Knockout pizza), had great, local brews and ice cream. We took surf lessons from Rusty and Homer at SoCal Surf lessons (it was SO fun) and enjoyed just being in the sun in the front yard.
A few tiny amenities would make this house really shine: a few games/cards, extra blankets, coffee and a few oils/spices/bottle of wine? Not necessary, but would be a nice touch. :)
We would definitely return.
