The apartment is located in a very charming and traditional neighbourhood. The owner wasn't there, but the communication was wonderful (from the very beginning, already). He left a women in his name who was the responsible to greet and guide us in our arrival. We have also instant contact with him by WhatsApp and Arbnb chat.
The apartment is big, bright and modern-decorated. The access has steep stairs, so watch out if you have heavy suitcases!
It was comfortable and also well equiped (you will need to buy some basics as caffee -capsules!, salt, sugar or oil if you want to cook. The rest -cutterly, fridge, pans, glasses or plates- is already available there.
The bedrooms and living room were simple, but cosy and with all the necessary. The bathroom seems to be quite new and there were a lot of towels and a hair dryer! There is a terrace too which was our main point of gathering together (the signal of the wifi in here is not as strong as in the rest of the apartment. Better for conversation!)
I have no complaints about my stay here. I am sure I'd repeat if I come back to Lisbon!
