Costa d'Este was a very lovely hotel with great staff. The only problem we had was the drinks at the bar were really watered down. I'm not a big drinker, so I notice when there's no alcohol. We spent the day on the beach in one of their little rented cabana's and it was a great time. It's important to wear sunscreen though, even when you're in the shade. We got fried!
The hotel it's self was immaculate. The rooms were contemporary and the hotel staff was friendly and accommodating. This hotel was definitely a good choice for us.
Oh also, I had a great massage while I was there. Oh my, it was simply lovely :)
