We chose this hotel because of it vicinity to Katoro beach, a nice snorkeling place for beginners. The hotel and the "residence" are different buildings but they share a restaurant (big enough for all), pools (nice but the pools were either too shallow, about 40 cm, or too deep, 1,35 m, for a 5-8 year old) and the waterpark, which is basically a pool with slides for smaller kids and a set of 3 slides for bigger ones. There was a nice selection of other activities as well, so you were not bored for sure. The rooms were fine, not outstanding but good for our stay. The breakfast selection was good, but unfortunately, I cannot comment on the dinner because somebody messed up our reservation, and the hotel only had as "bed and breakfast" instead of half-board, which we originally wanted to book. That was a very disappointing experience, and hotels.com did not help nor did they even get back to our messages.
The beach is a short walk from the hotel, it is all rocky though, clean but you must wear rock shoes. There are some restaurants and a market nearby, plus you can take a little train to Umag for sightseeing.
