Very lovely apartment in a great location in Valletta! We stayed here for 10 days and were very happy. Good wifi, hot water, working oven and kitchen, washing machine and all amenities you need. The apartment is in a good location, very central but far enough out of the main hub of Valletta that it's quiet at night.
We found the apartment quiet, though it's worth noting it's a residential street and in the mornings you can hear people talking to neighbours and cars beeping from time to time from around 8AM. This was no problem for us. You cannot hear any bars or other noise, and our sleep was never disturbed.
The apartment is on the ground floor and is really two rooms. We liked the open plan layout. One downside is that there is limited light as the only windows look directly out onto the street. We were happy to open those once we'd had our morning showers so it's fine but others may want more 'privacy' than this.
Overall, we very much enjoyed our stay. Communication with the host was fast and efficient, and Becky always went out of her way to help :)
