The place is very nice and clean, recently renovated with everything new - actually, I was reluctant when I did the booking as there were no reviews yet, but the apartment is as you see it in the pictures. The communication with the host was very good, they were always answering quickly and were very helpful.
The location is very good, practically in the city centre, I was always walking around to visit most of the historical neighbourhoods (Alfama, Chiado, Mouraria, Bairro Alto, etc). Tube and train station Cais do Sodre is literary across the street and you can also walk to Rossio train station to take the trains to Sintra.
The only issue I had was that the chairs are quite uncomfortable for sitting long hours and working remotely. The place is listed as having a "dedicated workspace", but actually the glass table and chairs are fine for eating or sitting for a while - I've got backaches when sitting and working for long hours.
One thing you should be aware of is that the windows are overlooking Rua Nova do Carvalho, the famous "pink Street" of Lisbon (actually this is where you will access the flat too, not via Rua Alecrim). The street turns lively and noisy at night as there are a lot of bars and restaurants. If you are a light sleeper, better bring some good earplugs to be able to sleep.
