A little tricky (as others have said) to find the right doors when arriving. Manos (the host) gives easy to follow directions; even if you arrive at midnight like I did. Otherwise, everything else was great.
Theiko_athens is a great coffee/sandwich shop across the street from the BnB. Six d.o.g.s is a great dinner/bar with an aweaome outdoor space just a few minutes away (went 3x in my 5 day stay 🤣).
10-15 min walk to acropolis. 5-10 min walk to Monastiraki square. 5 min walk to Athens' Central Market. (I walk a bit fast so times may vary)
