We spent almost two months at this apartment and our experience was really great, apart from about a week or two of uncomfortable heat and humidity in the apartment, which is quite common during peak summer months (Jun-Sept). Fortunately there are fans in every room which help.
The apartment offers a comfortable living area, a good working space (separate room with desk and office chair, which is ideal for working from home) - WiFi is fast and reliable with an extender for access throughout the entire apartment.
It's worthwhile to note that there's some noise to be expected from the restaurant below from about 8am until about lunch time, as well as noise from neighbouring apartment's air-conditioning, which is not too much of a problem unless you have the kitchen window or main bedroom sliding door open.
The location of the apartment is in close walking distance to Xlendi Bay, bay front dining and hiking trails which offer exquisite views. If you do not have a car, the bus stop is conveniently accessible, as is a small supermarket which is open daily until 9pm.
Communication with the host is great, she is very responsive and is always available for questions. You can check-in and check-out easily by yourself.
Overall we can recommend this apartment for short and long term stays.
