Great apartment and I had a good experience for a long stay of 1 month. Apartment was modern and clean inside but kept the charm of the surrounding old town. Well represented in the pictures.
Communication with hosts was good, had a walkthrough on check-in by a person organised by the host (host attended on a video call). Any questions were quickly answered by messages and were helpful. As it was a long stay, cleaning was provided which was very nice.
Internet connection via Wifi was good and dependable, it was fast enough for general browsing and video calling. Only dropped a few times very late at night but never became a particular issue for me.
Kitchen was useful and modernised, with equipment all there for a self catered short/long stay. Bathroom was clean and modern with good facilities. No washing machine inside, but there is a laundrette nearby.
Balcony was compact and quaint, was pleasant to sit out there though really only fits the table and chairs with a tight squeeze !
Location is central and convenient with Martim Moniz metro 5 minutes away and also on the door step of Alfama. Great routes to walking to the river and other locations around Lisbon, including being fairly close to mainline train stations for longer journeys outside the central area.
A great stay overall, with a pleasant apartment and pleasant hosts !
