Good communication before arrival and we managed to get into apartment by withdrawing keys from keyMaster lock. Finding the apartment was not difficult but with the big luggage, the steep slopes were rough. But it is like this everywhere in Porto! Luckily the building has lift. Mercados and mini marts around so getting essentials was easy. We were also allowed to store our luggage for an extra time as we waited for our train. The host is very kind and understanding.
It's a clean and very spacious apartment but only 2 of us this round, so hardly use the living room, also because it was really cold in the living room and kitchen during this time of yr. There is only 1 heater and it's in the bedroom. Also pointed out by a review here, the water pressure is very low, only 1 tap/faucet can be use at a time. So I cannot wash a cup if my friend is bathing.
