We had a great stay in Valletta at Maria's place. It is a compact flat which uses space well and has 2 of the famous traditional Valletta balconies looking out over the beautiful streets and lovely high ceilings. It is located in the thick of the city and a short walk to all the sights.
Maria had left a welcoming bottle of wine on the table for us which was a nice treat. If you are looking for a lie in, the streets were quite noisy at 7am, but as the city is fairly quiet at nights getting up early and exploring works well.
We had a great stay, the flat is a gem, we would recommend Maria and her flat wholeheartedly.
