Luis is a great host, very professional and responsive. The apartment is in excellent condition and very well located, in full barrio alto a few minutes by walk only from the Chiado and the main train/subway station - - and literally one minute from the famous tram 28. The fact that there is no AC was a bit difficult given that our stay coincided with a heat wave (max averaging 40 degrees during day time), but despite this we I still highly recommend this accommodation.
