Bernardino & Rui's friend met us to give us the keys and show us where the flat is which was great as it would have been difficult to find the flat otherwise. We were greeted with a bottle of wine which was a very nice touch. Bernardino & Rui were always quick to reply.
We were there during St. Antonio's festival during which the whole of Alfama transforms, there's lots of sardines being grilled, lively crowd and music until about 12 at night. Bernardino & Rui gave us a heads up the day before our arrival. Personally we enjoyed being in the middle of the festivities, but if you're looking for a quiet place and visiting in June maybe check the dates with them first.
The location of the flat is fantastic, with a great view and everything is within walking distance. Having said that the flat (especially the bathroom) is quite small. If you're on the taller side like my partner you might struggle a bit in the bathroom especially that the toilet seat is broken and the shower area is a bit fiddly. It was fine for our 3 day stay, but if you're staying for longer it might be difficult to unpack (lack of storage space) and settle in. All said we enjoyed our stay at the flat.
