We had an amazing stay. The host went beyond their duty to make us feel comfortable. We arrived Christmas day do we asked for a little groceries to go through the first night (found out that it was not needed as there was a local minimart just at door step open even on Christmas with all basic needs).the apartment occupy the whole 5th floor and has two comfy bedrooms and 2 bathrooms - 1 e suite.the apartment has all amenities (dish washer, washing machine, and all other kitchen small appliances, microwave, 2 hairdryers, etc. Plenty of electric heaters. Is located in a super central area, Cathedra just on the doorstep, Castle is a 10min hike. Street was quiet at night. Easy walk to the rest of the centre of Lisbon.
The only issue was noisy upstairs neighbours, that appeared to keep strange hours.
We strongly recommend this flat for your Lisbon trip, we couldnt have hoped for a better stay (noisy neighbours aside).
