We stayed at Rached's apartment on Praha at the beginning of 2018 and it was an amazing experience! I would recommend Rached's apartment to anyone who want to have a wonderful experience in a great place close to the old city centre. I would only tell you to avoid such apartment if you have any physical disabilitiy that unables you to climb the stairs, as the owner shows in the specification of the apartment that the building has no elevator. Otherwise, it is an amazing place, modern, cosy, fully equipped, with two comfortable bedrooms, balcony, great living room with kitchen and pool table.
I would also like to add the fact that every room was shown to us and if we had any issues, the owner was very kind and always available to help us. Also, as I said above, the apartment is close (10 min walk) from the city centre, train central station and bus central station (Florenc), and even more to the biggest mall in Praha, Palladium.
Enjoy Praha!
