Charlie's apartment was very modern, clean, great value for money and the pool was beautiful! It was perfectly located being a 5 minute walk from a metro station, and less than a 20 minute walk from the city centre. However when we arrived to check in we had to wait about half an hour to be let into the apartment, despite phone calling when we arrived at the airport. There was also a problem with the shower as it overflowed after a few minutes and flooded the bathroom, which obviously wasn't practical when 5 people needed to shower everyday. Despite this it was overall amazing, a really safe and homely place to come back to after exploring Lisbon. I would definitely go back!
