We had a wonderful time at Martin's apartment which is in the central area of Old Town Square - you couldn't get closer to the action if you tried. It is amazing to admire the view of the Astronomical clock from the living room window, an incredible sight as the tourists flock down below. Martin was a very kind and generous host, leaving us food and drinks for breakfast and making us feel at home. The apartment itself is so spacious and extremely clean. We visited in winter yet the apartment was super cozy and warm. Martin had some great tips of restaurants and activities and was only a text away if we needed anything. The only downside is that the apartment is up a few flights of stairs which wasn't a problem for us but may be for some people. Also we arrived at dark when the square was very busy and had a little bit of trouble finding the apartment so make sure you know where you are headed. Overall, a memorable experience and would definitely recommend!
