Me and my (retired) parents stayed at Pierre's & Miriam's place for longer period at the end stage of our trip around Portugal. We found the place to be just as described: very cozy, spacious, luminous, comfortable and very well located, for our needs. Since I had lived in Lisbon before, I was looking for authentic Lisbon feel.
Since we were staying for longer period, we knew we'd want to be away from tourist masses and feel the authentic Lisbon vibes. Also, I had been reading that this part of town is up-and-coming and wanted to be part of it.
Here in Marvila, the authenticity is still here. Small cafe's, barbershops, grocery stores.. locals only, rarely a random (literally lost) tourist. Everyone says good-day on the street and people are warm and welcoming. It was great to come here after a long day in downtown and smell the fresh air and enjoy the silence. Or join the local elderly men at the corner bar for a beer, smoke and football-watching or a game of cards.
Same time the area is very safe and the apartment is extremely well connected to city center with several bus lines e.g. 728 and express 781. 728 connects You via Cais do Sodre until Belem and 781 until Cais do Sodre. Train lines go towards Santa Apolonia, Entrecampos, Sete Rios, Alcantara, and red metro line to Airport. Closest bus stop and train (comboio) is 1-2 min walk, closest metro (Oriente) about 15 min walk. You can get to Praca de Commerca within 15-20 min and with train to Zoo or Alcantara on the other side of the city with same time, thanks to the various connection going from here. Oriente station also connects multiple long-distance trains. Same time there also runs nighttime bus (210 from Cais do Sodre) for if You don't want to Uber or Taxi Yourself home after a long night out.
Several bigger food shops (supermarkets), pharmacies etc in walking distance (10-15 min). Huge shopping mall at Oriente station.
Once this part of Tejo river used to be called the Factory Ghost Town, but now these factories are being taken over by local artists, small book stores and creative hubs. But again - not yet the hipsterlandia. One of the things I enjoyed really the most was the proximity of Parque das Nações and Expo. I'd spend my mornings walking around there, returning home for a breakfast and starting the day. Expo area offers beautiful walks, Oceonario (really worth Your time+money!), theaters, numerous restaurants, small parks etc.
Wifi works great. Lots of good books to read (French, German). Kitchen has all you need (and more). Apartment has small terrace (shared with neighbors). Beds are comfortable. Winter months are bit chillier but heaters did their job excellent. For those traveling with car - parking possible on the same street: free and safe. Exiting city with car is quick and time-saving from here.
We couldn't of had been more happy to be staying here.
