The apartment was clean, comfortable, fully stocked, excellent location. We were a group of 5 ladies. We each enjoyed having clean rooms and bathrooms (and hairdryers). The washer and dryer was really a nice to have when you need to pack light.
Several good pharmacies and mini markets surrounding the apartment so you can easily purchase necessities (water, toilet paper, meds, etc.).
You can easily walk to many tourist attractions within 15-20 minutes. The hills in certain neighborhoods may be a challenge if your not used to walking much but Uber is very easy to use.
The tram and train station was an easily accessible. We were able to easily purchase train tickets to visit Sintra for 5€ per person! Sintra is a must visit.
Martin and Mafalda were excellent hosts and responsive to our needs. W would absolutely stay again if we go back to Lisbon.
