Our stay at Samir's place was great, really close to the main strip in Vesterbro and also really convenient from the airport.
The place had everything we needed kitchenwise and otherwise and was super comfortable. We were three people but I think it would be fine for four if you needed.
The area around the apartment is really lively and the supermarket and a great food market are close too.
Samir gave us some good tips for getting around and surviving. Want to come again! Highly recommended!
