My sister and I spent 5 nights in Ramona's place. Overall, we enjoyed our time there and found it to be a good base from which to explore Valletta. However, we did encounter a few things that made our stay less than ideal.
Pros: Although Ramona was unable to meet us at check-in, everything went smoothly. She was available to answer our questions online. Ramona's place is a large maisonette with three floors, a private entrance and high-end finishes. It's beautiful, there is good air conditioning on each floor, two beautiful wooden balconies, and dependable wifi. We were just a few minutes walk from cafes, restaurants, and many of Valetta's sights.
Cons: The apartment does not have good sound-proofing. I am sure this stems from the fact that the unit is in a historical building but we certainly could hear our neighbours and were often bothered by the sound of cars and trucks barreling down the street at all hours of the night. We are not light sleepers or used to silence, this seemed unusually loud for us and was difficult to adjust to. Additionally, we didn't find the bed or pillows very comfortable, and the linens didn't seem to fit the size of the bed properly. We also found the toilet to be quite finicky- you have to press quite hard for several seconds to have enough water pressure to clear some waste and to be honest this meant that overall we tended to avoid using it if we could. Finally, we felt that staying in the maisonette came with a bit more rules than we would have liked. Romana asked that we take the garbage out each day and this meant arranging your day around the pick-up schedule. As clearly outlined in the description, you also have to be wary of your energy usage. While being conscious of your usage is always a good idea, it was a bit of a pain to worry about overage charges and wake up to turn the water heater on an hour before your shower. It's not that we found any of these requests unreasonable (they aren't and there are good reasons for them) we just found that they took away from our vacation experience in a way that wouldn't be a problem at a hotel or other property.
Although we likely wouldn't stay here again, we found Ramona's property to be beautiful and have several great features.
