Gisela's place was very nice for our little stay in Porto. The house has a few problems that can easily be fixed (peeling wallpaper, burnout light bulbs, ...) that can easily be fixed and don't impact the stay that much (just the experience).
Communication was a bit weird, since sometimes we would get what looked like automated messages in english (we're portuguese) and then other times what looked like genuine human messages in portuguese.
Other than that, we still believe it was a good stay and good value for money.
