Maria's apartment is in a great location. Plenty of bars, restaurants, parks within a short walking distance. Felt safe even walking alone after dark. Host was very polite and accommodated my early arrival time. Apartment was very tidy and clean, and great for extended periods of time, being that it had a washing machine + dishwasher. Main bathroom sink was a little stinky and the showerhead was a bit chaotic but serviceable. Wifi was slower than what I am used to in America, but I found this to be the case most places in Lisbon. Main bed was firm, which I liked because it is what I am used to.
TL;DR - fantastic location with plenty to do; few minor issues with bathroom; accommodating and friendly hosts.
Obrigado Maria and Laura!!!
