Manuel was very accommodating; we had some communication issues upon arrival (my fault), and he went above and beyond to rectify the situation.
The place was great, and exactly as presented in the listing. We were there on some of the hottest days of the year (35-39 celcius), and the apartment was warm, but since it was on the ground floor it stayed cooler than outside.
Manuel gave us a good overview of the apartment and the neighbourhood when we arrived.
The location was perfect: close to markets, restaurants, cafés, lounges, and bars/clubs (many of the city's gay bars are within a 5 minute walk). Noise from the bars was never an issue.
Some notes for Lisbon/Portugal from a Canadian/English-speaker's perspective:
You can get a Portuguese sim card from Vodafone. €10, provides unlimited data for 10 days, or €15 for unlimited text/calling + 1GB data. It will come in very handy when trying to get around.
Uber is an easy way to get around since you can enter the destination before you start your trip. Sometimes taxi drivers don't speak English, so it can be difficult to communicate with them. However, they will figure it out - even if they have to ask someone on the street.
Everyone is very helpful and welcoming. If you need help, just ask. People will even offer to help you if you seem lost or unsure.
Google Translate can make things easier if you don't speak Portuguese. The camera translator feature can be helpful when you want to scan something to read it.
The Portuguese generally eat dinner after 8:30, so many restaurants don't open until 7:30. The tourist areas may be an exception to this.
*The tapas restaurant that is 10m / 30 feet from the apartment is quite good. There are also some good places around the park (Jardim Fialho de Almeida) that is just around the corner.
