Marius and Daniela's apartment was great! It's a cute little studio with all the basic facilities that we needed. Everything was super clean, and the neighborhood was perfect, with alot of great cafes, restaurants and bars all within a block or two. Prague is really small, so you can get where you need to go fairly easily - all within a 30min walk or 10-20 mins by tram. There are plenty of trams just outside the door of the apartment block, so it is very convenient. Would definitely stay here again next time we are in Prague.
The only thing to note is that if you are here in summer and want to keep the big windows open for some fresh air and the summer breeze, it is VERY loud outside with the trams going every few minutes. You can barely hear it once you close the windows though. Also, the toilet is nor in the studio itself but out in the hallway.
