I had a very good experience in Maria's. Maria is very responsive and helped me with my requests. The flat is well located, five minutes walk from the Charles bridge. There are a lot of parks near by, so it's very convenient to find a place to have a promenade. Inside the flat, I had everything I need. I lived there for a month and didn't feel anything missing. I cooked most of my meals in the flat under the pandemic lockdown. There is also a bath tub which is definitely a plus in winter. The bed and sofa are very comfortable. The lighting system is nice as well. The heating runs 24/7, so I don't feel cold at all.
The only thing which can be improved is the internet speed. If you browse around the Internet or watch videos, there wouldn't be a problem. But I need to have video conferences all the time. The connection cuts in the middle very often.
In general, I would recommend Maria's flat. Will definitely live there again in the future.
