Alexandra's place is a stylish, modern apartment set in the old town. It is well furnished and equipped, and kept extremely clean and tidy. The bathroom was particularly fantastic.
Our only words of caution would be that the apartment is set half way up a steep hill (typical for the old town) and so it might not be the best location for people with mobility problems. It is also a ground floor apartment, so we found it quite strange in the mornings when tourists would peer in at us having coffee! It's also a slight pain as you have to be careful with keeping windows open (though they do open on a semi-locked basis).
We did also find that the walls are quite thin, so you can hear what is happening in the apartment upstairs and behind. But overall, it's a quiet place to stay.
Alexandra owns the entire building, which is made up of several apartments. It's therefore a safe place to stay, with a lock on the front door to the building. We kept our bags in the building hallway until our flight and it was fine - nothing stolen.
Communication was fantastic and the airport transfer was seamless.
We would definitely recommend this as a lovely place to stay. It's a short downhill walk to the main metro and bus stations and we found that Uber was quite cheap and easy.
