I wanted location to be away from busy tourist destinations so that I can have rest at night but convenient enough to quickly get to Alfama or Baixa. Lena's place is perfect for that purpose. It's very near bus, metro and train station and conveniently located between airport, shopping malls and downtown tourist destinations. There are several big grocery stores within walking distance and have decent options for breakfast as well such as Cafe Merendinha or A Padaria Portugesa. Both place accepts credit card so you will be ok in 1st day without euro.
