Tristan is very welcoming and responds quickly to messages. We left our luggage at the house before the check-in time and went sightseeing.
The place is nice and pretty well connected (bus and metro) which is good because it's in zone 3 (45 minutes from Victoria Museum).
Some quick fixes like a water pump for adequate pressure under the shower, some extra pans and dark curtains (to get a good night's sleep despite the street lights and 6AM sun) would be helpful.
