My stay in Odessa hotel was very pleasant and lived up to my expectations. The hotel standard was quite good for Ukraine and the room was nice as well. The staff was always helpful. I chose this hotel mainly for its extraordinary location. It is located on a pier and either overlooking the black sea or the city of odessa. Bear in mind that economy rooms are located in the middle floors of the hotel and for top floors you need to book luxury rooms. also for access to balcony and sea view.
Only small drawback was centrally controlled aircondition, so the room was a bit hot unless you opened the window facing the busy harbour including maintenance of the pier! Also the breakfast was only okay for ukrainian standard, but below scandinavian- but free of charge.
Finally, to correct a false statement: Taxis CAN drive all the way up to the entrance of the hotel, if the driver knows how. Especially, if you book the taxi in hotel reception, which is also cheaper than trying yourself as a tourist. Good luck!
