The hotel is in a fabulous location. The reception / bar / restaurant area is nice and pleasant enough. I didn't enjoy the breakfast, and I'm not normally a fussy person.
We booked a suite and our room was amazing. Very old fashioned furniture, huge, lovely balcony, lots of storage. BUT, the bed was uncomfortable and noisy at the smallest of movements.
The bathroom was a good size and the shower was powerful. No fan though so smelt a little musky at times.
The housekeeping was hit and miss. We were there for four nights and never had our bed changed. We had fresh towels every day but the room wasn't cleaned.
Sinaia is a wonderful place and I'm glad I went. If I ever went back, I'm not convinced I'd stay here again.
