We were overall happy with our stay but had some significant issues that would make this a property I would not recommend to a friend. The location was great and near the Alfama and central to everywhere you'd want to go. The living room was great and had nice little balconies over a little street with a few nice restaurants and coffee shops.
However, we ran into a couple of issues with amenities (limited towels for our five day stay, nespresso coffee maker but no pods, etc) and an issue where someone accessed the space while we were out one day - and we received no notice aside from coming home to find someone had been there. Also, while on vacation, there are two vital things - a clean bathroom and a nice bed. The bed was great but the bathroom was unfortunately a dread each morning as the shower had black mold, low pressure from the shower overhead and significant drainage issues that left us having to stand in a pool of water or stop our showers multiple times to let the water drain for fear of flooding the bathroom.
In the end, we had a lovely time in Lisbon but we will not be staying at this property again in the future.
