I stayed in Lisbon for a long weekend, and Nelson's place was just perfect. I was solo-traveling, and the small but cozy place was ideal for me. The apartment is very clean, the bed is comfy, and while there was a bit of bar noise on the street at night, I could not hear anything in the bedroom (which faces away from the street).
The apartment is very centrally located, in a picturesque tiny street, with easy access to public transport. You can start exploring the beautiful old town with many bars and restaurants right in front of your door. I could even make it to Carcavelos beach in ~45 minutes by walking + train.
Communication with Nelson was extremely friendly, check-in was easy and without any waiting. The best part, on my last day Nelson offered that I could stay a few hours beyond the regular check-out time, which allowed me for another beach trip just before my evening flight, without logistic hassle.
Loved my stay here, would definitely book again!
