Our stay at Marta's Apartment couldn't have been better. We were a fairly large group of 9 girls, and we all had more than enough room - as the apartment offered a total of 14 beds and a total of 6 bedrooms - we had more than enough space to accommodate everyone. The pictures of the apartment are also extremely accurate - balcony, living room, bathrooms, bedrooms etc.
The communication with Marta was also hassle free - she responded very quickly and was extremely cooperative - we even got a great list of restaurants, sightseeing tipps etc. We were thankfully allowed to do an early check-in, as we arrived fairly early in Lissabon. We could therefore freshen up and put our bags/suitcases in the apartment after the flight.
Other than that, the apartment was equipped with everything we needed - coffee, tea, a welcome cake, beer in the fridge, fresh towels, shower gel etc.
The apartment is also situated quite well and we generally took an Uber (super cheap) into the city.
Overall, I can only highly recommend Marta's apartment! We all enjoyed our stay very much!
