I stayed for a week and was there for dental work and mini vacation, and I booked the 2 bedroom Master Suite because I wanted the space and the view. Here's my honest review of Sina Suites...I'm trying to write the review that I wish I saw before I booked, and yeah I probably still would have booked.
Location: 7/10 It's slightly away, but still in somewhat reasonable walking distance, to the main areas of the Hotel Zone. I will say a good portion of the walk in between Sina and where everything is feels a bit sketchy at night in terms of both "bad guys" and wildlife, although I didn't have anything happen on my walks.
Quality of Room: 6/10 It's very basic and 3-star quality, mattresses were a bit sub-par. Was slightly disappointed because I paid close to larger/all-inclusive resort prices for the week. Upside was that it was clean, no bugs or any issues.
Overall Vibe: (Subjective) 8/10 It was great for me because I prefer a more chill experience and don't party, but others may prefer to stay elsewhere. I loved that it was relaxed and mostly quiet. Most common ages of guests ranged from 30s and up, and mostly couples.
Restaurant: 8/10 Food was good, service was great, view was excellent.
Staff: 10/10 Excellent staff, very professional and friendly.
Resort Nightlife: 5/10 The restaurant/bar closes at 10:30, go into town if you want to party.
Likelyness to Return: 8/10 I enjoyed my stay and would be very open to staying again.
Overall Score: 7.3/10
