I stayed at Joel's place for a month and a half and loved every minute! Joel doesn't live there but I met him briefly and, was easy to reach by phone and really willing to help. One of the five housemates is responsible for organisation and check in etc...everything went smoothly.
The location is central, near two metro lines and there are limitless places to eat nearby. My room was small but had a comfortable single bed, a desk with chair and an incredible view over Lisbon. Good kitchen and bathroom.
The house has a really friendly atmosphere and I met some great ppl.
Nearby recommendations: mu gelato (ice cream), fitnesshut (€7 per wk gym), asoficinas (affordable coworking space 10 mins walk away).
Thanks for a great stay. I hope to be back soon :)
