My stay at Marcus was overall satisfying. He was really reactive by messages and the house has a nice vibe and you don't feel on top of each other. Check in was easy room itself is nice if you are on your own, might feel a bit squashed if on your own. The terrace is a plus but the lock to close it is very difficult. There's a fan and AC (however the AC takes some time to cool the room).
The shared areas were ways clean overall I think general maintenance is needed in a few areas (common bathroom sink leaked, lack of good cooking ustensiles, stove not working really well & fan in the kitchen feeling it Can fall off very quickly).
The initial quoted price ($27/ night) on Airbnb is good value for money but if you book a week before Carnival be expected to pay double which you can find better value for money elsewhere to be fair.
The area itself is quite pleasant and has a bike station nearby, cafes, restaurants so I would recommend it
