We stayed two last nights of our wonderful Galapagos vacation in Santa Gruz and in Estrella del Mar in January 2012. We didn´t have anything booked ahead and just looked for a place to stay when we arrived. We had some requirements: a sea view with a balcony or terrace and a basic equipped but clean room near the town center with reasonable price. And we got all that - in Estrella del Mar! Other hotels with sea view were 3 times more expensive offering things we did not need.
There is no breakfast served, but there are several nice cafeterias in the main street to choose from. As someone mentioned, it is little bit tricky to find this hotel and you have to go down a dusty road from the main ave towards the sea (2 min walk), but it is very small town and there are impressively good signs to follow. And yes, they do not probably speak that much english there, which wasn´t a problem for us though, since we speak spanish. There was a fridge in the room and also aircon, however the AC was not very effective so the room was pretty warm even if it was on. But this was only review of one of the rooms they have, dont know about the others.
Only thing that annoyed us was the morning when we were leaving and needed a taxi to the airport. We had booked it ahead, but it never came even if we asked about it many times in the reception. And after some waiting we walked up to the main ave and took a taxi there instead.
