We stayed at Rob and Pavel's lovely apartment for a week, and it was an ideal base for us to explore Prague. It's situated in a great area (round the corner from the TV tower, which we highly recommend, and close to some nice restaurants and bars - much better than the ones in the touristy centre). It's about a 30-minute walk to the central train station, and about 40 to the Astronomical Clock.
We were met at the airport by Lukas, the driver Rob and Pavel had arranged for us - he, rather than Rob/Pavel, let us into the apartment, due to our late arrival, and he was also great company for the journey there. Everything was clean, tidy, and ready for our stay. The apartment is lovely and we felt very at home there right away. We especially loved the large balcony, which was the perfect place to enjoy breakfast or chill out after a long day sightseeing. Books (fiction as well as guidebooks/leaflets) and a folder jam-packed with thoughtful tips and suggestions from Rob and Pavel had been left out for us, and these really helped us get the most out of our stay.
We had a minor issue with a fuse tripping, but Pavel responded to my message really quickly and came round and sorted it all out the next day while we were out. So top marks on quick responses and sorting out any issues that might occasionally arise (these are the things can happen anywhere, so it's how they're dealt with that counts).
Overall, top marks to Rob and Pavel as hosts, and to this apartment as a lovely place to stay. We hope to return someday!
