We spent 4 nights at Victor's flat and we loved it! We never met the host, however the instructions provided by him before our arrival was everything we needed.
The sea is just across the street (maybe 15 metres away) so the view from the balcony on the second floor is amazing. However, the building is located on a hill so be prepared for heavy winds on the balcony from time to time.
The apartment is rather in older style, but this was not a problem at all. It's spacious and has all stuff you may need, except for the washing machine.
It's located in a very quiet area with not many tourists around which is great. The town of Marsalforn, with a small beach and several nice restaurants is a 10 minute walk away. It's about the same distance to the nearest shop. For sunbathing and swimming there's also a beach west from the apartment - Xwejni Bay, which is nicer and quiet.
All in all, we'd highly recommend Victor's apartment!
