Lovely flat in a traditional Porto building that was fully renovated - high ceilings, big windows, loads of light, bakeries and bars literally on your doorstep.
There's a small park right in front of the flat, and a great green view greeting you from your window.
I have been to Porto many times and can't recommend this location highly enough - Jardim de Sao Lazaro is right next the core historic city centre (Baixa do Porto) and yet is not a hugely busy area - you can walk to the historic city centre and still enjoy a quiet night of sleep!
Make sure you try the pulled pork sandwich in the restaurant to the left of the flat!
All in all highly recommended flat and area in Porto.
