Margarida is a gracious host and we benefitted from her recommendations for dining and sightseeing options. The apartment is centrally located - the only gripe we had were the occasional drunk tourists who were so loud and made us wake from our sleep. (Tourists, behave yourselves!)
If you're a Muslim traveller and is strict with food, there are a few Halal restaurants metres away.
As it is Ramadan and I'm fasting and can't eat and drink for 20hrs, I had to cook and eat breakfast at 4am. Margarida's kitchen is fully equipped for me to cook (I could not find a can opener though). If you need Asian food, there are 2 Asian food stores nearby to get dry ingredients and a nearby supermarket to get fresh produce. The door separating the living room/ kitchen and bedroom was great too as I was able to cook and eat at 4am while not disturbing my non-Muslim partner.
We found Lisbon a very lovely city and would choose to stay at Margarida' s place in a heartbeat!
