We were a group of 10 ppl who stayed at the Tower. We really enjoyed our stay as the hosts were wonderful and the place was very close to many attractions.
Firstly, the hosts accommodated us by letting us check in early due to having lots of luggage. They gave us directions to the apartment and even offered us transport.
Secondly, upon arrival Marketa spent time routing on the local maps places we should eat and places we should visit. She even offered for us to call her or email anytime if we needed help with sightseeing. Her tips were useful.
Lastly, the hosts let us check out late as our flight did not leave until the afternoon. This helped a lot as we had excessive luggage and couldn't carry 20 suitcases around Prague until it was time to depart.
Overall the experience of our stay was great. Only tip for larger groups traveling is if you are a group of 10 be prepared for a cosy stay as the apartment is not very spacious. I think this apartment is ideal for 6-8 ppl.
