My hubbie and I stayed in room 301 for 4 nights in March 2017.
Although our room had little in the way of a useable balcony, it was very well equipped in all other respects with lots of thoughtful touches such as a clothes horse, make up mirror and plenty of space.
Other room facilities included a super-king bed, Tv, mini bar, safe, bath with shower over, separate sink and make up area with hairdryer, toiletries, seating and bags of wardrobe space.
The breakfast was excellent, with a wide range of freshly prepared food and drinks in plentiful supply (fresh fruit, meats and cheeses, cooked English breakfast, breads, yoghurts, smoothies and cereals).
The gym and pool were added bonuses.
Staff were friendly and efficient and the entire hotel was spotless.
Although other hotels are better located, we enjoyed the walk along the front into the old town (30 mins) and Puerto Banus (60 mins).
Conclusion: The NH Marbella is a very well run hotel that's excellent value for money. We would definitely stay here again.
Enjoy!
