Marcell was a great host! Very easy to get in touch with, and very accommodating. The first night of our stay, he invited us to hang out in the garden with him and a few of his friends. We even got to try his Hungarian bean soup (which was AMAZING!).
The apartment was exactly as described, clean, secure, private, shower essentials were available, as were a few food items in the kitchen. Wifi is available, with a strong signal. TV is also available, though we didn't watch it. Marcell also procured an auxiliary cord to hook into his CD player so we could play music from our phones.
Location is great, but if you're not big on walking, I'd suggest having a car or bikes.
Marcell also helped us out immensely at the end of our stay - we needed to add an extra night, but couldn't stay in Green on Green, so he let us move into the ground floor apartment (look for it soon on Airbnb!) for the extra night, and for a discounted price.
Would definitely stay here again, in either apartment!!
