We stayed here for 10 days in October. This really is an excellent apartment with an almost ideal location for visiting Lisbon. You are right at the base of the Alfama, Uber/taxi is quickly available, and Praça do Comercio and ‘downtown’ is an enjoyable 10 minute walk. The apartment is spacious and comfortably furnished; Ohmm staff are attentive and helpful. (Be aware that given there is no air conditioning, in mid-summer it could be quite warm.)
