My family & I had a very comfortable stay at Maria's place. Maria was a great host, very responsive before and throughout our stay at her place. There was a small issue with the main bathroom sink when we arrived but she made sure to get it fixed as soon as possible. Liliana, who helped check us into the apartment, was also great and gave us very helpful info during check-in.
The place itself was quite clean and had all the amenities we needed for our 3 night stay. It looked very much the way it did in the photos posted. There is a nearby supermarket and lots of good restaurants. We preferred walking in Lisbon, and many of the sights were an easy walk from the apartment. I would definitely recommend Maria's place for an excellent time in Lisbon.
