We had a good stay at La Rose Sul Mare, but I think it is a fine line between a good stay and a bad stay, so here are some tips and insights from our time there. I had a really hard time finding recent reviews of the place and the older reviews (4+ years ago) did not paint the nicest picture. But also the complaints seemed manageable if you were prepared and set your expectations accordingly. I did and the stay overall was incredibly nice.
First and foremost, the place is gorgeous. The pictures are accurate, the room was pleasant, and the setting is absolutely stunning. I believe the place was full, but it was very quiet and there was zero battle for the pool or the sea deck area (although when we got there the main deck was under construction, but it was not something that bothered us.). We really only saw a handful of guests at one time. We hardly left the premises the two days we were there and loved it.
The staff is not exactly welcoming and mostly ignored us, which is fine when there are no issues. I had zero response before check-in and after, which I emailed a few times for clarification questions and to settle a bill I had not realized I had. They will not answer so don't bother. They even hung up on me several times.
Speaking of bills, they charge for everything and here is the sticking point. Almost everything is an "extra charge" (like the use of the kitchenette, fridge, etc.) but a lot comes included with the Airbnb listing (which apparently was not the case in the past). I was able to avoid all extra charges (I thought) so overall was happy, but it's also not a nice feeling when that is the only thing they are interested in talking about and left a bad taste with my partner.
There are also a lot of rules around eating and drinking on-site (and using a swimming cap in the pool) that feel like they are there so they can charge more. Again, probably the biggest complaint I heard - everything is an extra charge.
We had a car and opted to park outside the premises for free. You definitely need a car as there is only one place to eat within walking distance and ordering food can be a chore there. They don't want to take your order and it will be at least an hour wait. I believe the food comes from off-site.
But overall, as I managed to avoid (most) extra fees and the staff were not "un-friendly" (just indifferent) I would say it was a good trip. The views and location and overall place was stunning enough to make up for a less than cheerful staff and hotel vibe.
