We didn't meet Carlotta on this occasion as we came in at night from Sintra. Nonetheless, we were able to checkin smoothly by picking up the key from the restaurant downstairs. Carlotta was easily accessible by airbnb messages and sms to guide us with details like connecting onto wifi and details about the neighbouring area. The apartment is 'as is' per the photographs: roomy, clean and modern. We stayed as a group of 2, but there is certainly enough space for more. The location is pretty central on the road where Casa dos Bicos is. There are several restaurants on the street, so the area is safe at night and only 2 mins away from Praca da Commercio. Lisbon in general is a very safe city even for female travellers, but the area has a bit more of a rough and tumble feel towards the Alfama side. The flat isn't too noisy despite being on a busy traffic street and located on the first floor, although we had the windows closed at night to sleep. Really enjoyed the living room area to unwind after a long sightseeing day.
