It is a very well located flat. I think price wise is good.
It has small stairs (and many) so it is a bit difficult to go up-down with all the baby gear (stroller, etc).
There is a restaurant underneath, there for you can hear the fado singing from the flat (which is not so bad).
It is spacious and you have all the stuff to cook (all though no basic stuff like salt, pepper, etc).
All in all I think it is a good deal for the price and location!
