Stayed here for a week in August. Lovely big apartment, great location. Very handy for Alfama and the Cathedral, plenty good restaurants nearby too. Only a few minutes walk from Baixa-Chiado and Metro/trams to the rest of Lisbon.
Juan was great, good communication and information about check in etc. Like most of these historic apartment buildings in Lisbon there is no air conditioning, but there were 2 large fans/coolers in the bedroom and lounge so it wasn't a problem. Would stay again.
