Vera and her family are very helpful and welcoming! Our flight had delay and we checked in at around 11pm without any problem!
We had a wonderful time at their place, at the center of city and close to tons of shopping malls, bars and restaurants! If you are a book worm then you may also find many book store close to the house since it is located very close to the campus. Downtown is easily reachable by metro or bus within 20 min. A bus station is just located at the front door and metro is reachable by foot in less than 5 min (both yellow and red lines).
The only tips that we'd like to give to the future guests is: if you feel chilly at night you may find couple of extra blanket inside the sofa-bed in the hall, and if there is no water running in the pipes you need to go to the ground floor and open the main water valve for the apartment!
We'd definitely stay at Vera's place the next time we visit Lisboa!
