Just returned from my 3rd in 3 recent trips this year to Torrevieja, always staying at Casas En La Costa, in 3 different bungalows.
I've enjoyed all of my stays, and found the bungalows cosy and welcoming. The kitchens and bathrooms were well equipped, modern and spotlessly clean. The living rooms and bedrooms were comfortable. Family bungalows have wifi, which is a plus.
Location is great - easy walk to nice restaurants, shops and small parks. Secure, private urbanisation on top of a hill overlooking the sea, with mainly retired year-round residents, so it is very peaceful. Easy parking, and 5 mins to beach, N332, and 10 mins to centre by car.
The biggest plus for me is that my dog is welcome, and it is a very dog-friendly place to stay.
Finally, I cannot fault the service. Marta is very helpful and friendly.
Nothing really, but it might be nice to have more choice of satellite channels. They are CANAL +, so mainly Spanish channels, and a lot of English news channels. Good job I like news and current affairs! Also, Wifi = + laptop or tablet, and your own entertainment.
So, no, there is nothing I dislike about Casa En La Costa.
