The landlords were very helpful, they gave us various information in advance. Top service. A shuttle from the airport was also organized for €20.
An email was usually answered within an hour.
The apartment is relatively clear, only a small window in the bedroom and in the front door. The bathroom is very small and very old.
The bikes were in good condition, even helmets are provided. Alfama is on the mountain, just cobblestones and very narrow streets. We didn't drive.
The connection hose on the toilet was dripping, after a short email it was repaired the next morning and there was a bottle of red wine as compensation. Very nice.
