I'll travel to Armenia from 3rd to 12th July, having an AirBNB in Yerevan until the 10th - two more people would be allowed in the appartement which would be cool for sharing the cost (could also be for a shorter time between the 3rd and the 10th). I'll still check out if there's seperate rooms and separate keys.

Company on my day trips in the surroundings as well as within Yerevan would be cool, but depends on the compatibilities of your plans there and is not a must :)

Those include 1-2 days Yerevan as well as trips to Geghard & Garni (ideally on the same day), Chor Virap, Haghpat, Etchmiadzin & Zvartnoz and others, depending on the time
