This was my 3rd stay at Lucia's apartment. I guess that says a lot. So I'll copy-paste my previous review and add a few new comments. I stayed at Lucias's apartment for 5 days and could not have been happier with the place. Clean, well-equipped and perfect location. The apartment is very stylish and spacious (more than the pictures may have you believe) with a kitchen with all you need - including a good coffee-machine. It also has a good bed, nice bathroom, washing machine, dishwasher, aircon and fast and strong wifi. Recently Lucia added a new smart-tv, which is good for connecting to netflix etc. The apartment is facing a quiet courtyard, so no noise from the road nearby. A tram station is very close by and will take you anywhere in Prague. Getting to the town centre just takes about 5 minutes with the tram - or it is also just a 15 minutes nice walk through Letna Park. A reasonably large supermarket (Billa) is also close by, next to the tram station. Communication with Lucia was good and fast. She was also a very good, flexible and attentive host, and I would gladly book again if I return to Prague.
Update: Lucia has now added/changed the curtains in the bedroom since my last visit, making it a lot darker then it was before. A great addition, since it made the mornings in the room less bright.
