Roman and Quiterie have a beautiful apartment that is located in a quaint area. My two friends and I had an amazing stay while we were here. The place is very cozy and clean, and the best part is the terrace overlooking the river. We spent a lot of our time at the apartment on the terrace.
It is within a 2 minute walk to many of the bus stations and a 5-10 minute walk to the train station, so it is very easy to get to public transportation. There are also many attractions in walking distance from the apartment, and it's less than a 15 minute walk to the main square in Lisbon.
Although we didn't get to meet the hosts, they were very easy to communicate with before and during our stay. Susanna, whom we met, set us up in the apartment. She was also easy to reach and gave us a few recommendations.
I would definitely recommend staying here if you're traveling to Lisbon.
