I stayed a week as a solo traveller March 2020. I picked this hotel, as close to Primorski pool complex, and I am a keen swimmer.
The hotel was better than expected. Views from rooms on the front of the beach and sea are great. The maids are friendly and efficient. The reception/porter staff all helpful and keen to see you enjoy your stay. The breakfast was a good hot breakfast selection always stocked well.
They arranged a transfer for 10 Euros from the airport and someone was waiting for me when my flight landed, very easy. (You pay the hotel as part of the bill, not the driver)
I booked a single room, which tend to be at the back of the hotel, but on Day 2 upgraded to a seafront room, once I saw how wonderful the views were. It was well worth the upgrade and I was keen to support the hotel too, in a time where bookings are likely to drop due to the CV fearmongering around the world.
For some people, the traffic noise at the front might be offputting. I found it quietened down a lot from around 8pm to 7am, and often sat with my window open watching the view and listening to the waves break on the beach a little way away.
You do have to be inventive in the area, if you dont know any Bulgarian, as many people dont speak much English. The hotel was always a great place to come back too, as the receptionists spoke some English and always tried to help.
I hardly ever give top marks, but I have to this hotel, as it deserves it! Would stay again if I re-visit Varna.
