We arrived on a late-evening flight and had to wait outside for a while because we couldn't reach the hosts by phone. Apart from that, our stay was very good. The apartment was very clean and very well located. As written in the description, it is on the 4th floor but this has not been a difficulty. A Blue House store is practically next door, which is very helpful if anything is needed. Many nice bars are very close on foot but the apartment is very quiet. I would certainly recommend it for visiting Lisbon.
