78 steps of stairs. If you can overcome this, then you will rewarded by a nice flat with a homey feel. Alvaro is a good host, and his flat located on the 5th floor (or European 4th floor) is a gem which will make you feel like a local. It was problematic for us to get to his apartment because our bags are heavy. He did manage to have his neighbor/friend help us with our bags when we checked out. Alvaro made us feel at home during our stay and even left us some fruits and drinks in the fridge. Thanks Alvaro!
Quick tip if you have luggage: If you are using the train to get to his apartment, get off at Lavapies because thats the station with the elevator. Anton Martin does not have an elevator or escalator.
