A 100% recommendable apartment !
It has been very central and very clean.
The owner has checked very often if we need anything, and that we can always contact her if anything should happen. It was also very friendly that she prepared a book with all the recommended restaurants nearby and all the emergency numbers.
The check-in and check-out went without any problems.
Please note that the apartment is very close to some small bars ( we were of course informed about this in advance), for us this was not annoying as we were on holiday in Lisbon and always came home very late.
Maria was honestly very friendly and answered all our messages directly, we can recommend this apartment warmheartedly and this wonderful city as well !
