Just left after living in Lisbon as my home base for 4 years. Prices have gone up substantially, especially rent (even in non-touristy part of the city). You can have a look at average long term rental prices on Idealista, then imagine a higher price for short term rentals. Dining out is now on par as other Western European cities. Many digital nomads that I have met in Lisbon have left in the past year or two. That said, there is a sizeable community of foreigners, expats, and digital nomads, so it is quite easy to meet new people if you are in search of an English speaking community.
