We were warmly welcomed at our arrival in Elizabeth's apartment. The studio was exactly as described on Airbnb: clean, spacious, with a small kitchenette useful to make our own meals. The bed was quite soft but confortable and the bathroom had subfloor heating which was really enjoyable. There was a few food products in the apartment, like salt, pepper, sugar and two bags of tea and coffee.
Both the receptionists we met were lovable and helpful, giving us some tips about our visit of the city.

The apartment was part of the Royal Courts Hotel and Apartments, which is conveniently close to I.P. Pavlova subway and tram station (within 3 minutes walk). The place is reachable by a 40-minute travel from Prague airport, using bus 119 and subway.
From the apartment, you can reach the Old Town of Prague (Stare Mesto) in 8-10 minutes using the subway, or even do a nice walk of 25-30 minutes to arrive to the Old Town Square, the Astronomical Clock or Charles Bridge for instance.
If you want to visit the castle (N-W of the city), the tram 22 can directly lead you there in about 20 minutes.
There are some restaurants / pizzerias in the neighbourood (we haven't tried them nevertheless), a small supermarket and a Paul shop (perfect for casual breakfast !).

We highly recommend this place, which was really nice for the cheap price we paid.
