The apartment is in a great location surrounded by transport links and great food and drink nearby. We particularly enjoyed Salo, Basilio and Brunch and Cafe (all around the same block) as well as pizza in the Italian downstairs. We stayed in Lisbon for 8 days and thoroughly enjoyed it. The apartment is clean and is well-equipped. Check-in was easy and the host very helpful.
The master bed had a very hard mattress, which was not to our taste and we found quite uncomfortable- but I think this is personal preference.
Sometimes we could hear music (and singing) coming from the restaurants downstairs, so worth bearing in mind it can be a little noisy. We had our 3 year old daughter with us, who was woken up by the noise a couple of times, so worth beating in mind if you are traveling with kids.
However, the area is lovely and is great for getting around Lisbon.
