1) We offer a very affordable option with the Yerevan State University Guesthouse, which might be useful during the end of May peak season. But this one is at some 1.5 km (about 1 mile) distance from the conference venue - which will be at the American University of Armenia (40 Baghramyan Ave.)

Paiment is posiible on arrival.
2) There is a small hotel very close to the conference venue, called "Bass Boutique Hotel" (Address: Aygedzor st. 3/1). It is just 350 meters (0.2 miles) away from AUA.
3) A little bit down Baghramyan street, there is a much nicer/relatively new "Opera Suite Hotel" (Baghramyan 1st lane). It is about 1km (0.6 mile) away from the conference venue - some 15 min. walk.
We would recommend one of the above options for proximity and reasonable pricing, but of course you can also have a look at a range of others. Here are some general offerings from Hyur Service, which include both Bass Boutique Hotel and Opera Suite:
