What's most important for me: good communications and reliable hosts. Everything worked super smooth here. We got all details beforehand, met in time, got responses when necessary - so we never had that 'hopefully it works out feeling'.
The place is as described and super close to the beach. Being one block away is a plus actually as it is less windy and you have less crazy people in front of your door.
All the disadvantages are honestly described in the text (no sink in the kitchen), no A/C. Not that you would need one temperature wise but being that close to the beach and with no direct sunlight in the bedroom it has a slightly damp climate. Didn't bug us at all though.
Wireless is fast and reliable and has a direct LAN connection with network cable and a little work place. Perfect if you need to get some stuff done (you'll hopefully spent more time at the beach or in the lovely patio though).
TL,DR: friendly hosts, reliable, as described. Enjoy!
