The host was very helpful and thorough with his explanation of hoe to get there what to expect to pay in a taxi as well as what to do and see in the local area, although circumstances didn't enable us to meet, we managed to have a FaceTime chat with him at the end of our stay. He was very good at keeping us up to date with our questions and always replied within a short time.
He was also kind enough to leave a local mobile phone for us to use which came in handy as we had to meet friends who live in the city and this helped us to communicate with them without having to make expensive foreign mobile calls.
The apartment is in a fantastic location, right in the middle of the historical Alfama district, be prepared for lots of steep hills around the city. The apartment is only a 5 minute walk from the metro station, and has great views of the river and the local church.
