Well located and clean place. No troubles in the check-in process as the host seemed to be flexible and reachable all the time. I am not sure whether it is a good value for money as the apartment is very small (I do not recommend it for more than 2 people); same utensils were missing in the kitchen and I personally didn't like the quality of the bed linen & duvets (we were 4 people - they were almost not enough).
It is Alfama and climbing stairs should be expected but be aware there are 3 flights of narrow & steep stairs.
