We stayed at the Eurostars Oasis Marbella and really enjoyed it overall. The hotel has a very nice pool area, the staff were lovely, and the rooms were clean, modern, and comfortable.
The beach is about a 10-minute walk away. It’s not the nicest part of the beach in Marbella, but still very convenient. Puerto Banús is also within walking distance — it’s a bit of a long walk, but definitely manageable on foot.
One big plus for us was the free parking spots right in front of the hotel. We visited in April, so we’re not sure whether parking is still as easy during the summer high season, but it was very convenient at that time.
If possible, I would definitely recommend requesting a room with a pool view. Rooms facing the road still have a balcony, but the view is much less pleasant.
