Rebecca and Gabriel's apartment is in south-central Geneva, on the 4th (meaning 5th) floor, with a nice balcony. It's about five blocks from a tram that takes you to the central station and the UN agencies, which was perfect for me. Rebecca is very friendly and well-organized. She was traveling during my stay but she made sure I had everything I needed. No worries, no problems, nothing to distract me from an enjoyable stay in Geneva!
