Sungshik's flat was really wonderful - just as the pictures show, if not better. The location was ideal and my friend & I couldn't have asked for an easier check-in.
Only two of us stayed as we were working during our time in Lisbon and wanted somewhere with enough space so as not to get in one another's way, but the flat could easily accommodate six. The table made for a perfect workspace.
A few others have noted the noise from the main road; it is very loud if the windows are open but this didn't prove too much of a problem for me because the nights were cool and I could easily sleep with the windows closed (they're doubled glazed so cancel out much of the noise unless you have them open). It might have been a bit trickier in the height of summer.
All in all, a wonderful stay.
