The communication with the Hosts was simply excellent and I was allowed to use the flat much earlier than 3pm. The apartment is lovely - modern, clean, it has got everything you may need. There is a nice balcony overlooking one of the Lisbon's hills. There is a lift in this building and the location of the flat is superb - just a few steps away from the metro station and just two stops away from the city centre (Rossio station).
