The location is up a hill in a typical old street of Lisbon. Really charming. The situation is super central yet mostly quiet. Joao, the host, is available and responding really fast in case of trouble. The weather was sadly too cold to jump in the swimmingpool, but we enjoyed sunbathing around.
The appartment is a little bit tiny for three persons, but really clean and we were mostly out all of the time. I think it would be a perfect flat for a couple, more comfortable.
I would totally go back there again, and will recommend it.
