Three colleauges and I stayed here for three months during June, July and August when we were working in Lisbon. The neighborhood offer a lot of small and cozy restaurants and bars, and it's a 10-15 minutes walk into town and Bairro Alto.
My general opinion is that it is a great apartment, great location and really good hosts. Krunal and Anita lovely and always and always helped us out straight away whenever we had issues with something. Can highly recommend this place!
Having stayed there for three months, here are pros and cons:
* Good neighborhood - Close and quite calm during night. So nice bars and restaurants close by though. It's not noisy like Bairro.
* Nice apartment - Good beds (firm, like it!) and everything has a good standard
* Really good hosts - Always helpful.
Cons (not that many but things we noticed):
* Maybe not suitable for a long-term stay - For a weekend / week long trip these things does not matter, but we missed this during our stay: The common space is small so it was hard just 'hanging out' in the apartment if you wanted to stay at home for one night. The sofa barely took two persons, and other than that we had to have kitchen chairs. There is freezer in the apartment and the fridge was very small which made cooking and storing food harder.
* The garbage truck that comes every night at 1 am - If you close the window, you do not hear it. But there is always glass shattering so it can wake you up if your window is open :) This was only annoying for the two who had their rooms facing the street, the other two rooms that faced 'the city view' was not bothered.
Overall; Really great hosts and a good place which is really ideal for weekend trips and week-long stays since it's easy to explore the city from, is located in a central neighborhood and gives you good value for your money. For a long-term stay as ours (~3 months) you will miss having these common areas and being able to store food in the freezer and the fridge for cooking.
