For it's price, Nova Hotel is excellent: comfortable rooms, pleasant staff, good breakfast and strategic location. I was welcomed well with no hitches at the desk and complimentary tea and seasonal dried fruits to spark my taste buds when I got to my room. The room accommodated me, a solo traveler at the time, perfectly. It comes complete with the usual hotel room necessities. The staff responded quickly throughout my stay and had an outstanding command of English.
Food prices at the hotel were average, leaning on the expensive side. While the room service menu was quite limited, I tried a pizza which was delicious despite their mini restaurant at the lobby. However, thanks to it's strategic location close to the centron and a wealth of restaurants around the area, it was easy for me to walk and get a quick bite outside the hotel. The hotel is slightly hidden from the street view but hopefully in the future this can be resolved.
I found after several days of staying that my room was particularly dusty. I could imagine this can be troublesome for some people but for me it was not a big deal. On the other had, the hallways, lobby, and surroundings were kept generally clean throughout my stay.
Overall, Nova Hotel is quite a hidden gem in Yerevan, especially for picky solo travelers like me who like it cheap but homely. I recommend this hotel to small families, couples or anyone looking for a quick, no-nonsense stay in Yerevan.
