This is the best choise if u need lowest price for your sleeping place and cosy location going along with hospitable host who is able to speak english fluently.
Park Gorkogo is the best place to chill out in Moscow and its only within 10 mins on foot, here are lots of churchs, museums and restaurants nearby. 3 metro stations, tram and buses going to the centre. It is calm and not dangerous district.
I would provide you with lots of necessary advices and of course help u if needed!
