We booked Pedro and Claudia's apartment for two nights. The apartment is on the ground floor right in front of the street, situated in a very central district and very close to all means of transportation. We are not sure if apartment being in the ground floor is the reason or every apartment in Lisbon is in the same condition or not, but the first thing that came up as we entered to the apartment was an intense smell of humidity. As a first impression we thought the apartment was locked up for a very long time, but unfortunately that wasn't the case. We couldn't even breath and sleep at night, also of the noisiness of the building, so the next day we had to pack up and leave early. If you are allergic or have any illness we don't recommend this place. Even though Pedro's father Carlos came up and was very helpful, it was impossible to stay with the smell. As a note, we took a taxi to arrive the apartment. Be careful with the taxi drivers in Lisbon if you are considering to take so since they try to overcharge!
