Tiago is the friendliest and most welcoming host one could imagine! He even prepared a list of vegetarian places for me to try!
The apartment is very comfortable, and quiet during the day, and yes, it can be very noisy at night because of the bars directly downstairs - but if you stay out enjoying the city long enough, this wont bother you at all (just take some ear plugs in case you want to sleep early :) )
An abundance of restaurants around, my favourite was Os Petiscos on Rua Atalaia - great wine and friendly staff too!
Lisbon is a wonderful wonderful city and I will be back to visit for sure!
