The Paris Hotel at Երևան, Armenia, is a very good four-star hotel just a few meters afar from Republic square. The rooms are quite large and I even had a balcony (which I found unusual inside an inner-city). It is a high-class hotel but not exaggerated; I felt really well there. Breakfast is served on the 12th floor where you can also get dinner and drinks in the evening hours.
The breakfast was really nice with local specialities and a piano player was creating a nice atmosphere. If you want to buy something instead of using a minibar: there is a nice and surprisingly stylish supermarket just across the road. The Paris Hotel is definitely worth a recommendation and I would book again here.
