Margarida and her husband were wonderful, they showed us the flat and gave us many useful recommendations. The flat is very central, easy to get by foot almost everywhere in Alfama/Bairro Alto. The tube/bus stations are also very close to the flat. One thing to mention however is that the flat upstairs is very noisy, you were able to hear them very clearly. It wasn't a major issue, as it only happened at the weekend in the morning, however it's worth keeping that in mind. Apart from that, the flat and experience all together was great!
