Courtesy's apartment is a very beautiful and clean home that has many thoughtful details. Location is very good, right at the centre. Everything is easily accessible on foot and by public transport. The apartment is equipped with everything you need inside as well.
The house does not have heater, although there are many electric heaters available in every corner of the house and good blankets, in the winter it gets cold. However, we did not spend too much time at home,since we were exploring the whole day, so this was not a real problem for us.
Looking forward to coming back to Lisbon!
