The location is really nice in Príncipe Real, a close walk to most everything. The Glória Elevador (funicular) is close by in the event that walking up hills at the end of a long day is not your preference. The area is nice, restaurants close by, you can grab the 24E tram in less than a 5 minute walk; however, all of the tourist areas (Alfama, Chiado, Bairro Alto, Cais do Sodre) are all very walkable from the apartment. The internet worked great. There is no AC but generally the apartment was comfortable and there is a fan and dehumidifier. I’d highly recommend that if you take the metro to the apartment to get off at the Rato stop as the walk is much flatter than if you ride to Avenida (especially if you have heavy luggage). Overall, a great stay, secure building and very nice!
