Benjamina‘s place is located in a quiet residential neighborhood away from the city center. I felt safe coming home around midnight. We also took Uber several times coming home at night which costed us €5-11 depending on distance.
The building and unit is good and the elevator is a plus. The unit has a washer but not a dryer. you can hang them on the rack for drying. It takes about 2 days to dry them with the open windows. It's a 5-7 minutes walk to the nearest metro station. A 20-30 minutes metro ride with a transfer will take you to most tourist attractions.
Ben does not provide toiletries/cooking species. There is a mart a few minutes away that sell toiletries and groceries.
Overall, Ben‘s place is a good value place of lodging.
