The check-in process is easy and thanks to ON Host for allowing us to check-in earlier. The apartment is clean and located in a strategic location, just behind Lisbon Cathedral (different level). If you want to access the apartment through the cathedral, then you need to walk downhill in "S" to reach it within 5 mins walk. This road is accessible by small car only. Our tour van cannot enter and we have to wait at Lisbon Cathedral. There is tram 28 stop just in front of the cathedral so very easy for you to catch it from the apartment. If you prefer to walk on the flat road to reach apartment, must through Porta do Mar (no car access). On other hand, you need to fight 1 floor of staircase to reach the unit and beware that the steps are small and steep. Will be very difficult to carry up and down when you carry big luggage (like us). Good wifi and cooking stove. The only problem we had during the stay is the washing machine which wasn't walking (the start button has been spoiled and cannot press). Even the communication with the host is fast but was told someone will come to fix and didn't see anyone. I reminded the host another time but no one turned up in other day and also didn't update me. So i just gave up not to use the washing machine. However, washing machine is one of my key considerations before make booking. Building's sound proof is poor and you can hear foot steps from staircase and upper unit loud and clear. In our last night stay (we spent 5 nights here), our neighbor was playing music for whole night and only stopped at 6am. We don't care and still can sleep because too tired walking in Lisbon.
